i think one should use recursion here, something like this maybe

use strict;
use warnings;

my @charset = ( 0..9, "A".."F" );
rec( 8 );

sub rec {
    my $deep = shift;
    my $string = shift || '';
    if ( $deep-- ) {
        for my $char ( @charset ) {
            rec( $deep, $string . $char );
        }
    }
    else {
        print "$string\n";
    }
}

Quite so, since all the loops have the same bounds. ++ed
