[issue44524] __name__ attribute in typing module

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

There are some side effects of setting _name. In 3.9:

>>> class X(Annotated[int, (1, 10)]): pass
... 
>>> X.__mro__
(<class '__main__.X'>, <class 'int'>, <class 'object'>)

In 3.10:

>>> class X(Annotated[int, (1, 10)]): pass
... 
>>> X.__mro__
(<class '__main__.X'>, <class 'int'>, <class 'typing.Generic'>, <class 'object'>)

Now a subclass of an Annotated alias is a generic type. Should it be?
