    def __init__(self):
        super().__init__()

        pass

class Something(A, B):  # error: Multiple inheritance is not allowed because the following base classes contain `__init__` or `__new__` methods that may not get called: B

i originally didn't want to rely on checking constructor's implementation because it won't always be available eg. in stub files. but i guess there's no reason not to check it if it is available

it would also need to ensure that the super().__init__ call matches the signature of the other class's constructor
