I very much like this — though I would say it was dependent on the nullable
types RFC (like splat and variadics were codependent).
While I would like to see the introduction of a void type, I understand and
respect the limitations on the RFC.
However, one thing that I do think is missing, is the equivalent of Hacks
`$this` return type. You have `self` and `parent`, but I think without a
`static` equivalent you can break things:
class foo {
static public function instanceOf(): self {
return new static();
}
}
class bar extends foo { }
foo::instanceOf(); // new foo, this is fine, returns `self`.
bar::instanceOf(); // new bar, no longer `self`
