18 =head1 DESCRIPTION
19
20 This pragma tells the compiler to enable (or disable) the use of POSIX
21 locales for built-in operations (LC_CTYPE for regular expressions, and
22 LC_COLLATE for string comparison).  Each "use locale" or "no locale"
23 affects statements to the end of the enclosing BLOCK.
24
25 See L<perllocale> for more detailed information on how Perl supports
26 locales.
