That’s what Protocols are for

They don't work in the way you would think for dataclasses or at all for dicts/TypedDicts.

See this for dataclasses: https://github.com/python/mypy/issues/5374#issuecomment-8841....

This is a ridiculous example, because dataclasses and protocols are orthogonal: dataclasses (help) define data structures, while protocols define behaviour.
