install_issubclass_patch conflict with typing.py's check

Hi Vincent @aranega install_issubclass_patch patches the bulitin.issubclass . But typing code will validate the package name of your patched function, like following code for GenericType:

    def __subclasscheck__(self, cls):
        if self.__origin__ is not None:
            if sys._getframe(1).f_globals['__name__'] not in ['abc', 'functools']:
                raise TypeError("Parameterized generics cannot be used with class "
                                "or instance checks")
            return False
        if self is Generic:
            raise TypeError("Class %r cannot be used with class "
                            "or instance checks" % self)
        return super().__subclasscheck__(cls)

Is there a way to solve this conflict? -Andy

Hi Vincent, I think your current implementation will only be impacted by typing module in python3.6 and older. In 3.7, it works fine. I just migrate to 3.7 as a quick workaround and it won’t block me right now. -Andy

The last pyecore version get rid of the patch, so there is no more problem regardless of the used python version 😃
