New submission from Gregory P. Smith <g...@krypto.org>:
Python 3.7-3.10a1:
```
>>> List.__name__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.8/typing.py", 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__
'List'
>>> 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
https://docs.python.org/3/library/stdtypes.html?highlight=__name__#special-attributes
as well.
