Hi Pedro,

We could do this, but I do wonder if it might cause a lot of E_NOTICEs
to pop up for existing code, assuming we applied this to built-in PHP
functions.
I'm not sure.
The way Pedro described it, it wouldn't apply to any existing functions
because they wouldn't be declared void.
Obviously, type hints for internal functions are a bit weird anyway, but
there's no reason to assume that every function documented as void would
suddenly be annotated in the Engine as such and start returning notices.
