Re: 5.4's New De-referencing plus assignment

Hi Ralph! This (in it's current form) doesn't look like a good idea to me. You are only handling yet another edge case. ($foo = $bar = new A)->bar() would again not work. If we really want this kind of (expr)-> syntax, then it should really accept *any* expr. But I am not quite sure whether this will work out easily because in this case we can't be sue that expr is an object (but maybe it'll be simple, I just don't know).
