That regex won't capture files with UC letters

#!/usr/bin/perl
use warnings;
use strict;
# 744661 

my @var = [ 'foo.Bar',
      'for.bar',
    ];

for my $var(@var) {
    if ( $var =~ /^(__[-!#.0-9@-Z_a-z]+)$/ ) {
        print "\$var: $var\n";
    } else {
         print "no match!\n";
    }
}

If you're concerned about files like "foo.Bar", use the /i modifier.
