Sounds like "Don't Do That" to me :-)

Yep, but it might also be a source of confusion too.  There's no way
to help the programmer realize that they've screwed up when they do.

	for $index (@array) {
	   print "$_ is at position $index\n";		# Oops!
	}

In this example, the programmer may realize his mistake when he sees
" is at position 0", but in the real world, the body of the loop may
be *much* more complicated.  How do we help the programmer when he
screws up?
