- Jedi cannot really deal with __new__.
- A typeshed issue: "function" should not be defined in the stubs.
- Jedi cannot deal with the weird __call__: NotImplemented typing,
because it's recursive.
All these attributes can be seen when using `dir(type)`.
In the future we should be discussing if certain methods on object (like
__eq__) should really be there. IMO this should be defined on type where it
actually also appears when using `dir`.
