Excellent! Thanks chromatic !

I still find it curious that he calls the exists function in list context. I can't imagine I'm the only one who has been bitten by this.

From the return perldoc for those too lazy to look it up themselves: 

return EXPR
.......snip.......
If no EXPR is given, returns an empty list in list context,
the undefined value in scalar context, and (of course)
nothing at all in a void context.
