Re: Proposal for php7 class method return

Hey Daniel, I've been playing around with self for a while (mostly dealing with code-generators and inheritance), and what I found is that it doesn't really make sense as a type-hint, not even in interfaces. Besides the type-work to be done to do `function setValue($value) : myClass, what is the advantage of having self`?
