locale - Perl pragma to use and avoid POSIX locales for built-in operations
@x = sort @y; # ASCII sorting order
@x = sort @y; # Locale-defined sorting order
@x = sort @y; # ASCII sorting order again
This pragma tells the compiler to enable (or disable) the use of POSIX
locales for built-in operations (LC_CTYPE for regular expressions, and
LC_COLLATE for string comparison). Each "use locale" or "no locale"
affects statements to the end of the enclosing BLOCK.
