I can have a stab at getting `mypy_test.py` and `regr_test.py` to work with non-types dependencies. I don't know where to start when it comes to getting pyright and pytype to...

> Couldn't a script be made for that, and re-used. Quite possibly. My point was just that I haven't really looked at `pytype_test.py`, and don't really know how it works,...

I think we can maybe do both. I agree with @Akuli that the language in `create_baseline_stubs.py` is definitely outdated — nowadays, we're pretty keen to emphasise that contributors shouldn't have...

Mypy has to implement quite a lot of special-casing in order to support `super()` at all. I think it's pretty unlikely that mypy is going to add the necessary complexity...

I'm guessing all of these tests would break if something like #12712 was ever merged (there seems to be a consensus that it would be good to do something like...

> Further, it would be great if stubtest defines error codes/categories to ignore only those categories for a function/argument Yup: https://github.com/python/mypy/blob/0a720edb1489af6da63f0731cbc66263598a5a5d/mypy/stubtest.py#L108
