    Nice! Very nice! I had to look twice (hell, five times) at x=length. I am still trying to understand $c^lc$c^lc:
    my $c = 'a'; my $d = 'A'; $_ = 'stuff'; print $c^lc$c^lc; print $d^lc$d^lc;
    More importantly, i am trying to understand how one would even COME UP with that! :D

    jeffa most humbly bows
