by-ref return & inheritance

Hi! Right now, strict inheritance rules do not allow to override public function __get($name) with public function & __get($name) I think we may want to allow this (but not the reverse - overriding by-ref return with by-val should not be allowed). Since by-ref return still can be used in by-val context, it should not break the LSP. And it can be useful in some situations - __get having specific by-ref semantics is one of them.
