So long as it is not too clever.

Returning foreign instances is supported behaviour for __new__. (If the object returned from __new__ is not an instance, __init__ is not called.) I believe the current implementation is reasonable and prefer to keep it. If I use the traditional implementation, there will only be one instance, with no state, only methods. That's a rather poor excuse for an instance, and a class already is a singleton object with methods and (in this case) no state, so creating an instance as well adds nothing.

I will change the implementation if the consensus among senior devs is against it, but would prefer not to.
