[issue41517] Enum multiple inheritance loophole

[Tal Suhareanu]

sorry, I'll explain. by "when inheriting an implemented enum, we get a runtime error" I refer to this https://docs.python.org/3/library/enum.html#restricted-enum-subclassing

You shouldn't be able to subclass an enum, yet I just showed a loophole. my example code shows you can subclass an enum by using a trick, multiple inheritance.

I hope it's more clear now :)

btw it also works with regular Enum inheritance (I just used IntEnum for simplicity)
