Ok, static methods are now callable in Python 3.10. Moreover, @staticmethod and @classmethod copy attributes from the callable object, same as functools.wraps().

Thanks to this change, I was able to propose to PR 25354 "bpo-43680: _pyio.open() becomes a static method".

Serhiy: if you want to "Implement __get__ for C functions", I suggest you opening a new issue for that. To be honest, I'm a little bit scared by the migration path, I expect that it will require to fix *many* projects.
