Does this improve on the POSIX locale system? I can see that it would for Klingon, but for most purposes it seems simpler to (adapted from perllocale):

use POSIX qw( locale_h );
my $oldloc = setlocale( LC_COLLATE, 'fr-CA.ISO8859-1')
    or warn 'Locale missing', $!;
use locale;
# go on to sort things

That approach makes available all the locale knowlege that the C libs have.
