=head1 NAME

locale - Perl pragma to use or avoid POSIX locales for built-in operations

=head1 WARNING

DO NOT USE this pragma in scripts that have multiple
L<threads|threads> active.  The locale is not local to a single thread.
Another thread may change the locale at any time, which could cause at a
minimum that a given thread is operating in a locale it isn't expecting
to be in.  On some platforms, segfaults can also occur.  The locale
change need not be explicit; some operations cause perl to change the
locale itself.  You are vulnerable simply by having done a C<"use
locale">.

=head1 SYNOPSIS

@x = sort @y;      # Native-platform/Unicode code point sort order
    {
        use locale;
        @x = sort @y;  # Locale-defined sort order
    }
    @x = sort @y;      # Native-platform/Unicode code point sort order
                       # again

=head1 DESCRIPTION

This pragma tells the compiler to enable (or disable) the use of POSIX
locales for built-in operations (for example, LC_CTYPE for regular
expressions, LC_COLLATE for string comparison, and LC_NUMERIC for number
formatting).  Each "use locale" or "no locale"
affects statements to the end of the enclosing BLOCK.

See L<perllocale> for more detailed information on how Perl supports
locales.

On systems that don't have locales, this pragma will cause your operations
to behave as if in the "C" locale; attempts to change the locale will fail.

# A separate bit is used for each of the two forms of the pragma, to save
# having to look at %^H for the normal case of a plain 'use locale' without an
# argument.
