types.GenericAlias has extra __copy__ and __deepcopy__ in __dir__ #105487
Description
Repro:
>>> type A[X] = list[X]
>>> dir(A[int])
[..., '__copy__', '__deepcopy__', ...]We can access all other attributes, but not __copy__ and __deepcopy__:
>>> A[int].__copy__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'types.GenericAlias' object has no attribute '__copy__'. Did you mean: '__doc__'?
>>> A[int].__deepcopy__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'types.GenericAlias' object has no attribute '__deepcopy__'I am not quite sure what is the right thing to do here 🤔
