Does this mean, in the context of this RFC, that short-form lambdas won't have their own scope though? I think it's not clear from RFC. Example: // would this create $ret in the outer scope assuming $ret was not // defined array_map(fn($elt) => $ret[] = $elt, [1]); var_dump($ret); // NULL or array(1) ? Current implementation (available on 3v4l.org) does create a local scope, but it should probably be explicitly stated in the RFC (and docs, should the RFC get accepted).
