The following example shows isinstance causing a side effect


class Side:

    class Effect(Exception):
        pass

    def __getattribute__(self, name):
        raise Side.Effect()


isinstance(Side(), str)


I'd be inclined to see this as a bug as I wouldn't expect isinstance to cause any side effects.
