Hi Internals, whilst recently playing with return type hints on PHP 7 I noticed that "static" cannot be used as a valid return type. I'm not entirely sure whether this has been purposely prevented or not.
https://3v4l.org/LEXis The behaviour works it's just a parse error that's stopping it. It's fairly easy to get around this behaviour by using 'self' on the return hint however I'm not too sure how correct this is considering you might want to have that method be extendable. https://3v4l.org/rk4W6 I always considered 'self' to represent the class where the definition lies, and 'static' to mean the caller class (i.e. when using LSB) so it might be something that you'd want to define on the type hint. Do you think this is something we should allow into the type system? Thoughts?
