I agree that this is a bug. `types.Union` is also missing a __getitem__ implementation.

And `typing.Union` supports pickling while `types.Union` doesn't:

>>> pickle.loads(pickle.dumps(int | str))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: cannot pickle 'types.Union' object
>>> pickle.loads(pickle.dumps(Union[int, str]))
typing.Union[int, str]

I don't have a use case for pickling types but someone might.
