Oh yeah -- Py_EnterRecursiveCall/Py_LeaveRecursiveCall in abstract_get_bases would be simpler. Also, the set approach also probably still c-stack overflows on

class C:
    def __getattr__(self, attr):
        class A: pass
        class B: pass
        A.__getattr__ = B.__getattr__ = C.__getattr__
        return (A(), B())

issubclass(C(), int)
