> Implement __get__ for C functions. Of course it is breaking change so we should first emit a warning. It will force all users to use staticmethod explicitly if they set a C function as a class attribute. We can also start emitting warnings for all callable non-descriptor class attributes.

Well... such change would impact way more code and sounds to require a painful migration plan.

Also, it doesn't prevent to make static methods callable, no?
