VERSION
        v0.1.0

DESCRIPTION
    This class inherits from Unicode::Locale.

    Make sure to check the API of Unicode::Locale for its constructor and
    its methods.

    It also accesses the Unicode CLDR (Common Locale Data Repository) data
    using Locale::Unicode::Data

    It requires perl v5.10.1 minimum to run.

CONSTRUCTOR
        # American English
        my $us = Locale::Intl-&gt;new( 'en-US' );
        # Japanese Katakana
        my $ja = Locale::Intl-&gt;new( 'ja-Kana' );
        # Swiss German as spoken in subdivision of Zurich
        my $ch = Locale::Intl-&gt;new( 'gsw-u-sd-chzh' );
        # Hebrew as spoken in Israel with Hebrew calendar and Jerusalem time zone
        my $he = Locale::Intl-&gt;new( 'he-IL-u-ca-hebrew-tz-jeruslm' );
        # Japanese with Japanese calendar and Tokyo time zone with Japanese Finance numbering
        # translated from Austrian German by an unidentified vendor with private extension 'private-subtag'
        my $ja = Locale::Intl-&gt;new( 'ja-t-de-AT-t0-und-u-ca-japanese-tz-jptyo-nu-jpanfin-x-private-subtag' );

    Passing some overriding options:

        my $locale = new Locale::Intl( 'en-US', { hourCycle =&gt; 'h12' });
        say $locale-&gt;hourCycle; # h12

  new
    This takes a Unicode locale identifier and an optional hash or hash
    reference of options, and returns a new instance of Locale::Intl. For
    the syntax of locale identifier strings, see the Unicode documentation
    &lt;https://www.unicode.org/reports/tr35/&gt;.

    A "locale" is composed of a "language", such as "fr" (French) or "ja"
    (Japanese) or "gsw" (Swiss German), an optional "script", such as "Latn"
    (Latin) or "Kana" (Katanaka), a "region", which can be a country code,
    such as "US" (United States) or a world region, such as 150 (Europe) and
    a "variant", such as "valencia" as in "ca-ES-valencia". Only the
    "language" part is required.

    The supported options are:

    *   "calendar"

        Any syntactically valid string following the Unicode type grammar
        &lt;https://unicode.org/reports/tr35/#Unicode_locale_identifier&gt; (one
        or more segments of 3窶�8 alphanumerals, joined by hyphens) is
        accepted. See getAllCalendars() for all the supported calendars.

        See also "calendar" in Locale::Unicode

    *   "caseFirst"

        This is the case-first sort option. Possible values are "upper",
        "lower", or a false value, such as "undef" or 0.

        See also "colCaseFirst" in Locale::Unicode

    *   "collation"

        Any syntactically valid string following the Unicode type grammar
        &lt;https://unicode.org/reports/tr35/#Unicode_locale_identifier&gt; is
        accepted. See getCollations for a list of supported collations.

        See also "collation" in Locale::Unicode

    *   "hourCycle"

        Possible values are "h23", "h12", "h11", or the practically unused
        "h24", which are explained in getHourCycles

        See also "hour_cycle" in Locale::Unicode

    *   "language"

        Not to be confused, this is a part of a broader "locale". Any
        syntactically valid string following the Unicode language subtag
        grammar &lt;https://unicode.org/reports/tr35/#unicode_language_subtag&gt;
        (2窶�3 or 5窶�8 letters) is accepted.

    *   "numberingSystem"

        Any syntactically valid string following the Unicode type grammar
        &lt;https://unicode.org/reports/tr35/#Unicode_locale_identifier&gt; is
        accepted. See getNumberingSystems for the numbering systems
        supported for the "locale" set in the object, or
        getAllNumberingSystems for the list of all supported numbering
        systems.

        See also "number" in Locale::Unicode

    *   "numeric"

        The numeric sort option. This takes a boolean value.

        See also "colNumeric" in Locale::Unicode

    *   "region"

        Any syntactically valid string following the Unicode region subtag
        grammar &lt;https://unicode.org/reports/tr35/#unicode_region_subtag&gt;
        (either 2 letters or 3 digits) is accepted.

    *   "script"

        Any syntactically valid string following the Unicode script subtag
        &lt;https://unicode.org/reports/tr35/#unicode_script_subtag&gt; grammar (4
        letters) is accepted, but the implementation only recognizes certain
        kinds.

        See also "script" in Locale::Unicode

METHODS
  getAllCalendars
    This is a read-only method that returns an array of all possible
    calendar values supported by the current version of LDML (Locale Data
    Markup Language) &lt;https://unicode.org/reports/tr35/&gt;.

  getAllNumberingSystems
    This is a read-only method that returns an array of all possible
    numbering system values supported by the current version of LDML (Locale
    Data Markup Language) &lt;https://unicode.org/reports/tr35/&gt;.

  getAllTimeZones
    This is a read-only method that returns an array of all possible time
    zone values supported by the current version of LDML (Locale Data Markup
    Language) &lt;https://unicode.org/reports/tr35/&gt;. Please note that to
    ensure consistency, the LDML supports some values that are either
    outdated or removed from IANA's time zone database.

  getCalendars
        my $jaJP = new Locale::Intl( 'ja-JP' );
        say $jaJP-&gt;getCalendars(); # ["gregory", "japanese"]

    This method returns an array of one or more unique calendar identifiers
    for this "locale".

    See the Unicode Locale BCP47 extensions for the list of valid calendar
    values.

  getCollations
        my $locale = Locale::Intl-&gt;new( 'zh' );
        say $locale-&gt;getCollations(); # ["pinyin", "stroke", "zhuyin", "emoji", "eor"]

    The "getCollations()" method returns an array of one or more collation
    types commonly used for this locale. If the Locale already has a
    "collation", then the returned array contains that single value.

    If the locale identifier object does not have a "collation" already,
    "getCollations()" lists all commonly-used collation types for the given
    locale identifier.

    See the Unicode Locale BCP47 extensions for the list of valid collation
    values.

  getHourCycles
        my $jaJP = Locale::Intl-&gt;new( 'ja-JP' );
        say $jaJP-&gt;getHourCycles(); # ["h23"]

        my $arEG = Locale::Intl-&gt;new( 'ar-EG' );
        say $arEG-&gt;getHourCycles(); # ["h12"]

    This method returns an array of one or more unique hour cycle
    identifiers commonly used for this locale, sorted in descending
    preference. If the Locale already has an hourCycle, then the returned
    array contains that single value.

    If the locale identifier object does not have a "hourCycle" already,
    this method lists all commonly-used hour cycle identifiers for the given
    locale.

    Below are the valid values:

    *   "h12"

        Hour system using "1窶�12"; corresponds to "h" in patterns. The 12
        hour clock, with midnight starting at "12:00" am. As used, for
        example, in the United States.

    *   "h23"

        Hour system using "0窶�23"; corresponds to "H" in patterns. The 24
        hour clock, with midnight starting at "0:00".

    *   "h11"

        Hour system using "0窶�11"; corresponds to "K" in patterns. The 12
        hour clock, with midnight starting at "0:00" am. Mostly used in
        Japan.

    *   "h24"

        Hour system using "1窶�24"; corresponds to "k" in pattern. The 24 hour
        clock, with midnight starting at "24:00". Not used anywhere.

    Hour cycles usage in the world are:

    *   "h12 h23"

        115 locales

    *   "h23 h12"

        95 locales

    *   "h23"

        60 locales

    *   "h23 h11 h12"

        1 locale

    See also the property hourCycle

  getNumberingSystems
        my $ja = Locale::Intl-&gt;new( 'ja' );
        say $ja-&gt;getNumberingSystems(); # ["latn"]

        my $arEG = Locale::Intl-&gt;new( 'ar-EG' );
        say $arEG-&gt;getNumberingSystems(); # ["arab"]

    This method returns an array of one or more unique numbering system
    identifiers commonly used for this locale, sorted in descending
    preference. If the Locale already has a numberingSystem, then the
    returned array contains that single value.

    See the Unicode Locale BCP47 extensions for the list of valid numbering
    system values.

  getTextInfo
        my $ar = Locale::Intl-&gt;new( 'ar' );
        say $ar-&gt;getTextInfo(); # rtl

        my $es = Locale::Intl-&gt;new( 'es' );
        say $es-&gt;getTextInfo(); # ltr

    This method returns a string representing the ordering of characters
    indicated by either "ltr" (left-to-right) or by "rtl" (right-to-left)
    for this locale as specified in UTS 35 Layouts Elements
    &lt;https://www.unicode.org/reports/tr35/tr35-general.html#Layout_Elements&gt;
    .

  getTimeZones
        my $jaJP = Locale::Intl-&gt;new( 'ja-JP' );
        say $jaJP-&gt;getTimeZones(); # ["Asia/Tokyo"]

        my $ar = Locale::Intl-&gt;new( 'ar' );
        # This will resolve to Africa/Cairo, because the locale 'ar' 
        3 will maximize to ar-Arab-EG and from there to Egypt
        say $ar-&gt;getTimeZones(); # ["Africa/Cairo"]

    This method returns an array of supported time zones for this locale.

    ach value is an IANA time zone canonical name
    &lt;https://en.wikipedia.org/wiki/Daylight_saving_time#IANA_time_zone_datab
    ase&gt;, sorted in alphabetical order. If the locale identifier does not
    contain a "region" subtag, the returned value is "undef".

    Keep in mind that the values do not necessarily match the IANA database
    that changes from time to time. The Unicode LDML keeps old time zones
    for stability purpose
    &lt;https://unicode.org/reports/tr35/#Time_Zone_Identifiers&gt;.

    Also note that this method behaves slightly differently from its
    JavaScript counter part, as the JavaScript getTimeZones() method
    &lt;https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Globa
    l_Objects/Intl/Locale/getTimeZones&gt; will return "undef" if only a
    "language" subtag is provided and not a "locale" tha would include a
    "country code". This method, instead, will maximize the 2-letters
    "locale" provided and from there will returns the time zone for the
    default country for that language.

    See also getAllTimeZones to get a list of all available time zones.

  getWeekInfo
        const he = Locale::Intl-&gt;new( 'he' );
         say $he-&gt;getWeekInfo();
         # { firstDay =&gt; 7, weekend =&gt; [5, 6], minimalDays =&gt; 1 }

        const af = Locale::Intl-&gt;new( 'af' );
        say $af-&gt;getWeekInfo();
        # { firstDay =&gt; 7, weekend =&gt; [6, 7], minimalDays =&gt; 1 }

        const enGB = Locale::Intl-&gt;new( 'en-GB' );
        say $enGB-&gt;getWeekInfo();
        # { firstDay =&gt; 1, weekend =&gt; [6, 7], minimalDays =&gt; 4 }

        const msBN = Locale::Intl-&gt;new( 'ms-BN' );
        say $msBN-&gt;getWeekInfo();
        # { firstDay =&gt; 7, weekend =&gt; [5, 7], minimalDays =&gt; 1 }
        # Brunei weekend is Friday and Sunday but not Saturday

    This method returns an hash reference with the properties "firstDay",
    "weekend" and "minimalDays" for this locale, as specified in UTS 35 Week
    Elements
    &lt;https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Patterns_Week
    _Elements&gt;.

    *   "firstDay"

        An integer indicating the first day of the week for the locale. Can
        be either 1 (Monday) or 7 (Sunday).

    *   "weekend"

        An array of integers indicating the weekend days for the locale,
        where 1 is Monday and 7 is Sunday.

    *   "minimalDays"

        An integer between 1 and 7 indicating the minimal days required in
        the first week of a month or year, for calendar purposes.

  maximise
    This is an alias for maximise

  maximize
        my $english = Locale::Intl-&gt;new( 'en' );
        my $korean = Locale::Intl-&gt;new( 'ko' );
        my $arabic = Locale::Intl-&gt;new( 'ar' );
    
        say $english-&gt;maximize()-&gt;baseName;
        # en-Latn-US
    
        say $korean-&gt;maximize()-&gt;baseName;
        # ko-Kore-KR
    
        say $arabic-&gt;maximize()-&gt;baseName;
        # ar-Arab-EG

    This method gets the most likely values
    &lt;https://github.com/unicode-org/cldr-json/blob/main/cldr-json/cldr-core/
    supplemental/likelySubtags.json&gt; for the "language", "script", and
    "region" of this locale based on existing values and returns a new
    Locale::Intl object.

    Sometimes, it is convenient to be able to identify the most likely
    locale language identifier subtags based on an incomplete "language" ID.
    The Add Likely Subtags algorithm
    &lt;https://www.unicode.org/reports/tr35/#Likely_Subtags&gt; gives us this
    functionality. For instance, given the "language" ID "en", the algorithm
    would return "en-Latn-US", since English can only be written in the
    Latin script, and is most likely to be used in the United States, as it
    is the largest English-speaking country in the world. This functionality
    is provided via this "maximize()" method. "maximize()" only affects the
    main subtags that comprise the "language" identifier: "language",
    "script", and "region" subtags. Other subtags after the "-u" in the
    "locale" identifier are called extension subtags and are not affected by
    the "maximize()" method. Examples of these subtags include hourCycle,
    calendar, and numeric.

    Upon error, it sets an exception object and returns "undef" in scalar
    context, or an empty list in list context.

    Example:

        my $myLocale = Locale::Intl-&gt;new( 'fr', {
            hourCycle =&gt; 'h12',
            calendar =&gt; 'gregory',
        });
        say $myLocale-&gt;baseName; # fr
        say $myLocale-&gt;toString(); # fr-u-ca-gregory-hc-h12
        my $myLocMaximized = $myLocale-&gt;maximize();

        # The "Latn" and "FR" tags are added
        # fr-Latn-FR
        # since French is only written in the Latin script and 
        # is most likely to be spoken in France.
        say $myLocMaximized-&gt;baseName;

        # fr-Latn-FR-u-ca-gregory-hc-h12
        # Note that the extension tags (after '-u') remain unchanged.
        say $myLocMaximized-&gt;toString();

  minimise
    This is an alias for minimise

  minimize
        my $english = Locale::Intl-&gt;new( 'en-Latn-US' );
        my $korean = Locale::Intl-&gt;new( 'ko-Kore-KR' );
        my $arabic = Locale::Intl-&gt;new( 'ar-Arab-EG' );

        say $english-&gt;minimize()-&gt;baseName;
        # en

        say $korean-&gt;minimize()-&gt;baseName;
        # ko

        say $arabic-&gt;minimize()-&gt;baseName;
        # ar

        my $myLocale = Locale::Intl-&gt;new( 'fr-Latn-FR', {
            hourCycle =&gt; 'h12',
            calendar =&gt; 'gregory',
        });
        say $myLocale-&gt;baseName; # fr-Latn-FR
        say $myLocale-&gt;toString(); # fr-Latn-FR-u-ca-gregory-hc-h12

        my $myLocMinimized = $myLocale-&gt;minimize();

        # Prints 'fr', since French is only written in the Latin script and
        # is most likely to be spoken in France.
        say $myLocMinimized-&gt;baseName);

        # fr-u-ca-gregory-hc-h12
        # Note that the extension tags (after '-u') remain unchanged.
        say $myLocMinimized-&gt;toString();

    This method attempts to remove information about this "locale" that
    would be added by calling maximize(), which means removing any language,
    script, or region subtags from the locale language identifier
    (essentially the contents of baseName).

    This is useful when there are superfluous subtags in the language
    identifier; for instance, "en-Latn" can be simplified to "en", since
    "Latn" is the only script used to write English. "minimize()" only
    affects the main subtags that comprise the language identifier:
    "language", "script", and "region" subtags. Other subtags after the "-u"
    in the locale identifier are called extension subtags and are not
    affected by the "minimize()" method. Examples of these subtags include
    hourCycle, calendar, and numeric.

    This returns a new Locale::Intl instance whose baseName property returns
    the result of the Remove Likely Subtags
    &lt;https://www.unicode.org/reports/tr35/#Likely_Subtags&gt; algorithm
    executed against "$locale-&gt;baseName".

  toString
        my $french = Locale::Intl-&gt;new('fr-Latn-FR', {
            calendar =&gt; 'gregory',
            hourCycle =&gt; 'h12',
        });
        const korean = Locale::Intl-&gt;new('ko-Kore-KR', {
            numeric =&gt; 'true',
            caseFirst =&gt; 'upper',
        });

        say $french-&gt;toString();
        # fr-Latn-FR-u-ca-gregory-hc-h12

        say $korean-&gt;toString();
        # ko-Kore-KR-u-kf-upper-kn

    This method returns this Locale::Intl's full locale identifier string.

    The string value is computed once and is cached until any of the
    "locale"'s attributes are changed.

PROPERTIES
  baseName
        # Sets locale to Canadian French
        my $myLoc = Locale::Intl-&gt;new( "fr-Latn-CA" );
        say $myLoc-&gt;toString(); # fr-Latn-CA-u-ca-gregory
        say $myLoc-&gt;baseName; # fr-Latn-CA

        # calendar to Gregorian, hour cycle to 24 hours
        my $japan = Locale::Intl-&gt;new( "ja-JP-u-ca-gregory-hc-24" );
        say $japan-&gt;toString(); # ja-JP-u-ca-gregory-hc-h24
        $japan-&gt;baseName; # ja-JP

        # Dutch and region as Belgium, but options override the region to the Netherlands
        my $dutch = Locale::Intl-&gt;new( "nl-Latn-BE", { region =&gt; "NL" });
    
        say $dutch-&gt;baseName; # nl-Latn-NL

    The "baseName" accessor property of Locale::Intl instances returns a
    substring of this "locale"'s string representation, containing core
    information about this locale.

    Specifically, this returns the substring containing the "language", the
    "script" and "region" if available.

    See Unicode grammar ID
    &lt;https://www.unicode.org/reports/tr35/#Identifiers&gt; for more
    information.

  calendar
    This returns the calendar type for this locale.

    The "calendar" property's value is set at object instantiation time,
    either through the "ca" attribute of the "locale" identifier or through
    the "calendar" option of the Locale::Unicode constructor. The latter
    takes priority if they are both present; and if neither is present, the
    property has value "undef".

    For a list of supported calendar types, see "getCalendars" in
    Locale::Intl.

    For example:

    Adding a "calendar" through the "locale" attribute.

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, "calendar" era types are
    "locale" attribute "extension subtags". These subtags add additional
    data about the "locale", and are added to "locale" identifiers by using
    the "-u" extension. Thus, the "calendar" era type can be added to the
    initial "locale" identifier string that is passed into the Locale::Intl
    constructor. To add the calendar type, first add the "-u" extension to
    the string. Next, add the -ca extension to indicate that you are adding
    a calendar type. Finally, add the calendar era type to the string.

        my $locale = Locale::Intl-&gt;new( 'he-IL-u-ca-hebrew-tz-jeruslm' );
        say $locale-&gt;calendar; # hebrew

    Alternatively, you could also achieve the same results, using the
    methods inherited from Locale::Unicode:

        my $locale = Locale::Intl-&gt;new( 'he-IL' );
        $locale-&gt;ca( 'hebrew' )-&gt;tz( 'jeruslm' );
        say $locale-&gt;calendar; # hebrew

    Adding a "calendar" type via the optional hash or hash reference of
    options.

    The Locale::Intl constructor takes an optional hash or hash reference of
    options, which can contain any of several extension types, including
    calendars. Set the "calendar" property of the optional hash or hash
    reference to your desired "calendar" era, and then pass it into the
    constructor.

        my $locale = Locale::Intl-&gt;new( 'he-IL', { calendar =&gt; 'hebrew' } );
        say $locale-&gt;calendar; # hebrew

  caseFirst
    The "caseFirst" accessor property of Locale::Intl instances returns
    whether case is taken into account for this "locale"'s collation rules.

    There are 3 values that the "caseFirst" property can have, outlined in
    the table below.

    *   "upper"

        Upper case to be sorted before lower case.

    *   "lower"

        Lower case to be sorted before upper case.

    *   "false"

        No special case ordering.

    Setting the caseFirst value via the locale string

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, the values that "aseFirst"
    represents correspond to the attribute kf. "kf" is treated as a "locale"
    string "extension subtag". These subtags add additional data about the
    "locale", and are added to "locale" identifiers by using the "-u"
    extension attribute. Thus, the "caseFirst" value can be added to the
    initial "locale" identifier string that is passed into the Locale
    constructor. To add the "caseFirst" value, first add the "-u" extension
    key to the string. Next, add the -kf extension key to indicate that you
    are adding a value for "caseFirst". Finally, add the "caseFirst" value
    to the string.

        my $locale = Locale::Intl-&gt;new( "fr-Latn-FR-u-kf-upper" );
        say $locale-&gt;caseFirst; # upper

    Setting the "caseFirst" value via the optional hash or hash reference of
    options.

    The Locale::Intl constructor takes an optional hash or hash reference of
    options, which can be used to pass extension types. Set the "caseFirst"
    property of the configuration object to your desired "caseFirst" value,
    and then pass it into the constructor.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US", { caseFirst =&gt; "lower" });
        say $locale-&gt;caseFirst; # lower

  collation
    The "collation" accessor property of Locale::Intl instances returns the
    "collation" type for this "locale", which is used to order strings
    according to the "locale"'s rules.

    The "collation" property's value is set at object instantiation time,
    either through the co attribute of the locale identifier or through the
    "collation" option of the Locale::Intl constructor. The latter takes
    priority if they are both present; and if neither is present, the
    property has value "undef".

    For a list of supported collation types, see getCollations().

    For example:

    Adding a collation type via the locale string.

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, "collation" types are "locale"
    attribute "extension subtags". These subtags add additional data about
    the "locale", and are added to locale identifiers by using the "-u"
    extension. Thus, the collation type can be added to the initial locale
    identifier string that is passed into the Locale::Intl constructor. To
    add the "collation" type, first add the "-u" extension to the string.
    Next, add the "-co" extension to indicate that you are adding a
    collation type. Finally, add the collation type to the string.

        my $locale = Locale::Intl-&gt;new( "zh-Hant-u-co-zhuyin" );
        say $locale-&gt;collation; # zhuyin

    Adding a collation type via the configuration object argument.

    The Locale::Intl constructor has an optional hash or hash reference of
    options, which can contain any of several extension types, including
    "collation" types. Set the "collation" property of the configuration
    object to your desired "collation" type, and then pass it into the
    constructor.

        my $locale = Locale::Intl-&gt;new( "zh-Hant", { collation =&gt; "zhuyin" });
        say $locale-&gt;collation; # zhuyin

  hourCycle
    The "hourCycle" accessor property of Locale::Intl instances returns the
    hour cycle type for this locale identifier.

    There are 2 main types of time keeping conventions (clocks) used around
    the world: the 12 hour clock and the 24 hour clock. The "hourCycle"
    property's value is set upon object instantiation, either through the hc
    attribute of the locale identifier or through the "hourCycle" option of
    the Locale::Intl constructor. The latter takes priority if they are both
    present; and if neither is present, the property has value "undef".

    For a list of supported hour cycle types, see getHourCycles().

    For example:

    Like other "locale" subtags, the hour cycle type can be added to the
    Locale::Intl object via the locale string, or an option upon object
    instantiation.

    Adding an hour cycle via the locale string

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, hour cycle types are locale
    attribute "extension subtags". These subtags add additional data about
    the "locale", and are added to locale identifiers by using the "-u"
    extension. Thus, the hour cycle type can be added to the initial locale
    identifier string that is passed into the Locale::Intl constructor. To
    add the hour cycle type, first add the "-u" extension key to the string.
    Next, add the "-hc" extension to indicate that you are adding an hour
    cycle. Finally, add the hour cycle type to the string.

        my $locale = Locale::Intl-&gt;new( "fr-FR-u-hc-h23" );
        say $locale-&gt;hourCycle; # h23

    Adding an hour cycle via the configuration object argument

    The Locale::Intl constructor has an optional hash or hash reference of
    options, which can contain any of several extension types, including
    hour cycle types. Set the "hourCycle" property of the configuration
    object to your desired hour cycle type, and then pass it into the
    constructor.

        my $locale = Locale::Intl-&gt;new( "en-US", { hourCycle =&gt; "h12" });
        say $locale-&gt;hourCycle; # h12

  language
    The "language" accessor property of Locale::Intl instances returns the
    "language" associated with this "locale".

    Language is one of the core features of a "locale". The Unicode
    specification treats the "language" identifier of a "locale" as the
    "language" and the "region" together (to make a distinction between
    dialects and variations, e.g. British English vs. American English).
    However, the "language" property of an Locale::Intl object returns
    strictly the "locale"'s "language" subtag. This subtag can be a 2 or
    3-characters code.

    For example:

    Setting the "language" in the locale identifier string argument.

    In order to be a valid Unicode locale identifier, a string must start
    with the "language" subtag. The main argument to the Locale::Intl
    constructor must be a valid Unicode locale identifier, so whenever the
    constructor is used, it must be passed an identifier with a "language"
    subtag.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US" );
        say $locale-&gt;language; # en

    Overriding language via the configuration object.

    While the "language" subtag must be specified, the Locale::Intl
    constructor takes an hash or hash reference of options, which can
    override the "language" subtag.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US", { language =&gt; "es" });
        say $locale-&gt;language; # es

  numberingSystem
    The "numberingSystem" accessor property of Locale::Intl instances
    returns the numeral system for this "locale".

    A numeral system is a system for expressing numbers. The
    "numberingSystem" property's value is set upon object instantiation,
    either through the nu attribute of the locale identifier or through the
    "numberingSystem" option of the Locale::Intl constructor. The latter
    takes priority if they are both present; and if neither is present, the
    property has value "undef".

    For a list of supported numbering system types, see
    getNumberingSystems().

    Adding a numbering system via the locale string.

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, numbering system types are
    "locale" attribute "extension subtags". These subtags add additional
    data about the "locale", and are added to "locale" identifiers by using
    the "-u" extension. Thus, the numbering system type can be added to the
    initial "locale" identifier string that is passed into the Locale::Intl
    constructor. To add the numbering system type, first add the "-u"
    extension attribute to the string. Next, add the -nu extension to
    indicate that you are adding a numbering system. Finally, add the
    numbering system type to the string.

        my $locale = Locale::Intl-&gt;new( "fr-Latn-FR-u-nu-mong" );
        say $locale-&gt;numberingSystem; # mong

    Adding a numbering system via the configuration object argument.

    The Locale::Intl constructor has an optional hash or hash reference of
    options, which can contain any of several extension types, including
    numbering system types. Set the "numberingSystem" property of the hash
    or hash reference of options to your desired numbering system type, and
    then pass it into the constructor.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US", { numberingSystem =&gt; "latn" });
        say $locale-&gt;numberingSystem; # latn

  numeric
    The "numeric" accessor property of Locale::Intl instances returns a
    boolean object representing whether this "locale" has special collation
    handling for "numeric" characters.

    Like "caseFirst", "numeric" represents a modification to the collation
    rules utilized by the locale. "numeric" is a boolean value, which means
    that it can be either true or false. If "numeric" is set to "false",
    there will be no special handling of "numeric" values in strings. If
    "numeric" is set to "true", then the "locale" will take "numeric"
    characters into account when collating strings. This special "numeric"
    handling means that sequences of decimal digits will be compared as
    numbers. For example, the string "A-21" will be considered less than
    "A-123".

    Example:

    Setting the numeric value via the locale string.

    In the Unicode locale string specifications
    &lt;https://www.unicode.org/reports/tr35/&gt;, the values that "numeric"
    represents correspond to the attribute kn. kn is considered a locale
    string extension subtag". These subtags add additional data about the
    locale, and are added to locale identifiers by using the -u extension
    key. Thus, the "numeric" value can be added to the initial locale
    identifier string that is passed into the Locale::Intl constructor. To
    set the "numeric" value, first add the "-u" extension attribute to the
    string. Next, add the "-kn" extension attribute to indicate that you are
    adding a value for "numeric". Finally, add the "numeric" value to the
    string. If you want to set "numeric" to true, adding the kn attribute
    will suffice. To set the value to false, you must specify in by adding
    "false" after the kn attribute.

        my $locale = Locale::Intl-&gt;new("fr-Latn-FR-u-kn-false");
        say $locale-&gt;numeric); # false

    Setting the numeric value via the configuration object argument.

    The Locale::Unicode constructor has an optional hash or hash reference
    of options, which can be used to pass extension types. Set the "numeric"
    property of the hash or hash reference of options to your desired
    "numeric" value and pass it into the constructor.

        my $locale = Locale::Intl-&gt;new("en-Latn-US", { numeric =&gt; $true_value });
        say $locale-&gt;numeric; # true

  region
    The "region" accessor property of Locale::Intl instances returns the
    "region" of the world (usually a country) associated with this "locale".
    This could be a country code, or a world region represented with a
    3-digits code

    The "region" is an essential part of the locale identifier, as it places
    the "locale" in a specific area of the world. Knowing the "locale"'s
    region is vital to identifying differences between locales. For example,
    English is spoken in the United Kingdom and the United States of
    America, but there are differences in spelling and other "language"
    conventions between those two countries.

    For example:

    Setting the region in the locale identifier string argument.

    The "region" is the third part of a valid Unicode language identifier
    string, and can be set by adding it to the locale identifier string that
    is passed into the Locale::Intl constructor.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US" );
        say $locale-&gt;region; # US

        my $locale = Locale::Intl-&gt;new( "fr-Latn-150" );
        say $locale-&gt;region; # 150
        # 150 is the region code for Europe

    See the file "territories.json" in the CLDR repository
    &lt;https://github.com/unicode-org/cldr-json/tree/main/cldr-json/cldr-local
    enames-full&gt; for the localised names of those territories.

  script
    The "script" accessor property of Locale::Intl instances returns the
    "script" used for writing the particular "language" used in this
    "locale".

    A "script", sometimes called writing system, is one of the core
    attributes of a locale. It indicates the set of symbols, or glyphs, that
    are used to write a particular "language". For instance, the "script"
    associated with English is Latin ("latn"), whereas the "script" used to
    represent Japanese Katanaka is "Kana" and the one typically associated
    with Korean is Hangul ("Hang"). In many cases, denoting a "script" is
    not strictly necessary, since the language (which is necessary) is only
    written in a single "script". There are exceptions to this rule,
    however, and it is important to indicate the "script" whenever possible,
    in order to have a complete Unicode language identifier.

    For example:

    Setting the script in the locale identifier string argument.

    The "script" is the second part of a valid Unicode language identifier
    string, and can be set by adding it to the locale identifier string that
    is passed into the Locale::Intl constructor. Note that the "script" is
    not a required part of a locale identifier.

        my $locale = Locale::Intl-&gt;new( "en-Latn-US" );
        say $locale-&gt;script); # Latn

    Setting the "script" via the hash or hash reference of options.

    The Locale::Intl constructor takes an hash or hash reference of options,
    which can be used to set the "script" subtag and property.

        my $locale = Locale::Intl-&gt;new("fr-FR", { script =&gt; "Latn" });
        say $locale; # fr-Latn-FR
        say $locale-&gt;script; # Latn
