There is a rule: equal hashable objects should have the same hash. The unity type violates it. >>> x = int | str >>> y = str | int >>> x == y True >>> hash(x) == hash(y) False And hashes of equal unity type and typing.Union are different too. >>> import typing >>> z = typing.Union[int, str] >>> x == z True >>> hash(x) == hash(z) False There is also a problem with a single type (see issue44636). |
