The backdoor command fo() uses isinstance() to check if an object is an instance of a class. This only works with objects that have a __class__ attribute, else an AttributeError is raised by isinstance(). This is seldomly the case, though if there is one such object fo() will cease to work. Therefore we need to protect us against this case by checking for a __class__ attribute before calling isinstance(). An example for an object without __class__ would be functools._lru_list_elem.
