Python 3.7-3.10a1:
>>> List.__name__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.8/", line 760, in __getattr__
    raise AttributeError(attr)
AttributeError: __name__
>>> type(List)
<class 'typing._SpecialGenericAlias'>
>>> type(List[int])
<class 'typing._GenericAlias'>

Python 3.6:
>>> from typing import List
>>> List.__name__
>>> type(List)
<class 'typing.GenericMeta'>
>>> type(List[int])
<class 'typing.GenericMeta'>

Is this lack of common meta attributes intentional?  It makes the typing types unusual.

We just saw it trip up some code that was expecting everything to have a `__name__` attribute while moving beyond 3.6.  Judging by that `__getattr__` implementation it should happen on other common `__` attributes as mentioned in as well.
