in thread negating POSIX regexp classes doesn't work as expected

I don't think one needs use POSIX, at least with the more recent versions of perl; e.g. with v5.8.4: 

#!perl -l

use strict;
use warnings;

my $s = 'a1b2c3';

print for $s =~ /[[:alpha:]]/g;
print for $s =~ /[[:digit:]]/g;
__END__

    You are correct, sir. I had thought it was use POSIX that caused it to bark at me when I didn't have the doubled brackets (POSIX syntax [: :] belongs inside character classes in regex), but it seems that it will bark without it. In either case, it only barks for positive char classes like [:digit:], not for negated ones like [:^digit:].
