You call count but don't do anything with the return value

It's printed at the end.

The last value assigned to the (lexically declared file) global `$result` is printed. Nothing is done with the (implicit) return value from the sub `count` where it's called.</nitpick> But yes eventually it's used. I was writing these in order as I read along so I didn't notice that action-at-a-distance because I glossed over the declaration on first read. Personal habit/preference is for a functional style (or OOP-y setters/getters at the worst :) and void context just looks plain wrong. The cake is a lie. The cake is a lie. The cake is a lie.
