Subject: Re: scrambler one-liner

This is hilarious, because a friend and I just had (over lunch) a race
to see who could code it up first.  I used Ruby and he used Perl.  Mine
worked first, but then I reworked it a bit to make it neater.  His was
impossible to read, but I totally have to send him this one-liner.  Man,
sort_by{rand} is so awesome!  I can't believe I didn't think of that!
