Apparently (++$count) evaluates to 0, but I can't figure out why. So the second
expression is evaluated first. From there it's pretty self-explanatory. (++$count)
will always evaluate to TRUE, since it will only get higher, and the first expression
is evaluated.
Maybe someone can enlighten us to some of the lesser known properties of the -- and ++
operators? It's definitely counterintuitive.
