I wonder why this test (and/or its result) does not depend on php version

Nice, almost perfect 😊 But I think we're missing a few things:
- It should support
@throws voidas a means to mark "this does not throw exceptions". - It should respect
$this->implicitThrows. When throwType isnull, if this property is true, it means an implicit throw point should be added. If this property is false, it means that__toStringdoes not throw an exception.
There's already code in NodeScopeResolver handling these things - getMethodThrowPoint. Should be possible to reuse it.
