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 🤔
