for :class:`collections.abc.Callable` are now flattened while
:data:`typing.Callable`'s have not changed. To allow this change,
:class:`types.GenericAlias` can now be subclassed and
``collections.abc.Callable``'s ``__class_getitem__`` will now return a
subclass of ``types.GenericAlias``. Tests for typing were also updated to
not subclass things like ``Callable[..., T]`` as that is not a valid base
class. Finally, both ``Callable``\ s no longer validate their ``argtypes``,
in ``Callable[[argtypes], resulttype]`` to prepare for :pep:`612`. Patch by
