Sub of is returning a list into a scalar context. That gives you the length of the list, not the first element as you seem to want.

Also, @y = map { $_-1 if mumble } @_ gives you a list that contains undefs where mumble is false. That means $#y is always equal to $#_.

Update: Thanks for the correction, Randal. I had to read it a couple of times, but you're exactly right, of course.
