The problem is that __module__ is deduced from the caller's frame in type.__new__(). In case if type.__new__() is called directly, __module__ is set to the name of the module where type.__new__() is called. So virtually every type subclass which defines the __new__ method and calls type.__new__() inside it starves from the same issue. It can be fixed in general if deduce __module__ in type.__call__() instead of type.__new__().
