        my $locale = DateTime::Locale::FromCLDR->new( 'es' );
        my $script = $locale->variant;
        # undef

        # No such thing as variant 'klingon'. Language 'tlh' exists though :)
        my $locale = DateTime::Locale::FromCLDR->new( 'en-klingon' );
        my $script = $locale->variant;
        # ''

    Returns the name of the "locale"'s "variant" in English.

    If there is no "variant" specified in the "locale", it will return
    "undef"

    If there is a "variant" in the "locale", but, somehow, it cannot be
    found in the "en" "locale"'s language tree, it will return an empty
    string.

  variant_code
        my $locale = DateTime::Locale::FromCLDR->new( 'es-valencia' );
        my $script = $locale->variant_code;
        # valencia

        my $locale = DateTime::Locale::FromCLDR->new( 'es-ES' );
        my $script = $locale->variant_code;
        # undef

    Returns the "locale"'s "variant" ID, or "undef" if there is none.

  variant_id
    This is an alias for variant_code

  variants
        my $locale = DateTime::Locale::FromCLDR->new( 'es-valencia' );
        my $array = $locale->variants;
        # ["valencia"]

        my $locale = DateTime::Locale::FromCLDR->new( 'ja-Latn-fonipa-hepburn-heploc' );
        my $array = $locale->variants;
        # ["fonipa", "hepburn", "heploc"]

        my $locale = DateTime::Locale::FromCLDR->new( 'en' );
        my $array = $locale->variants;
        # []

    This returns an array reference of "variant" subtags for this "locale",
    even if there is no variant.

  version
        my $locale = DateTime::Locale::FromCLDR->new( 'en' );
        say $locale->version; # 45.0

    Returns the Unicode "CLDR" data version number.

SERIALISATION
    "Locale::Unicode" supports Storable::Improved, Storable, Sereal and CBOR
    serialisation, by implementing the methods "FREEZE", "THAW",
    "STORABLE_freeze", "STORABLE_thaw"

    For serialisation with Sereal, make sure to instantiate the Sereal
    encoder with the "freeze_callbacks" option set to true, otherwise,
    "Sereal" will not use the "FREEZE" and "THAW" methods.

    See "FREEZE/THAW CALLBACK MECHANISM" in Sereal::Encoder for more
    information.

    For CBOR, it is recommended to use the option "allow_sharing" to enable
    the reuse of references, such as:

        my $cbor = CBOR::XS->new->allow_sharing;

    Also, if you use the option "allow_tags" with JSON, then all of those
    modules will work too, since this option enables support for the
    "FREEZE" and "THAW" methods.
