I'm sure there are a lot of ways to do that, but I'd probably go with
my ($x, $y, $z) = (split(',', $_), '' x 3);
which does the split, but also puts empty strings onto the end of the list. Then your variables grab the first three items from the list, running into the empty strings if they run out of data from the split.

Update: ambrus is right. That's what I get for testing code without warnings on.

    [Corion]: Oh yay. Thanks to The New Firefox, my irc client ChatZilla doesn't work anymore either... So I'll have to keep an old FF around just for that...
    [Corion]: 100% of my FF add-ons are unsupported currently. Maybe upgrading Firefox wasn't such a good idea after all ;)
