Yes. That's my point. I don't like that error.

You should probably try the example you're trying to post before posting it.

Okay. How about this then:
class MM(type):
def __subclasscheck__(self, subclass):
return issubclass(subclass, type)
class M(type, metaclass=MM):
pass
class N(type):
pass
class C(metaclass=M):
pass
class D(metaclass=N):
pass
class E(C, D, metaclass=N):
pas
You forgot something in that example I think because it doesn't actually do
anything that can "not work".
