Well... nothing then, as I thought he claimed that on 4.3 it wouldn't
throw a notice.

I agree with Nuno: E_NOTICE on undefined variable access is (almost)
global, so we should not start documenting this everywhere.
5.0.3 DOES return 0 if undefined.
Derick: If something changed, what is it?

I don't agree with that change, because if we add such info to count()
we would have to add it to all functions.
If you use an uninitialized var in PHP, you will get a E_NOTICE. This
isn't specific to count().
