The nice thing about Protocols is that they are so easy to define, you can just define them yourself. There's no need to have a "standard" protocol in typing.py for ever single dunder method in existence.
PS. There's no need for `__slots__ = ()` assuming you're not going to inherit directly from it (there's really no point).
