It seems that int doesn't have a method stub for __new__, which causes mypy to complain on code that attempts to subclass int. Unfortunately, I'm not sure exactly how to write this stub. If someone can give me some guidance, I can try to write a pull request.

    int.__new__ had been added in #1352 but then reverted in #1464

    So I guess it's not possible to add a stub for int.__new__ without breaking other things? Does this mean I just need to use # type: ignore on the call to super(...).__new__() when subclassing int?
