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.
