Not being a regular on this list, I want to ask if there is history of discussion of a "something or nul" return type declaration for PHP 7.
I'm only interested in this narrowly defined change, the PHP equivalent of a `/** @return Something|null */` dockblock tag *without* generalizing to `/** @return A|B|C... */`. If this is already argued to death, or even just a bit, I'd like to read the RFC(s) and discussion. Grateful for pointers. Tom
