Pah, we all know the future is psp

Just to be clear: I'd be happier without type hinting then type hinting
throwing an E_ERROR (a E_WARNING would also make me happy).
The problem I have is the 1% of the time where a type mismatch doesn't
get caught, running normal code on a production site, and it causes a
bailout. I can imagine that's going to cause quite a few errors
(display_errors off, hard to reproduce bug).
