Quite interesting.  So you are saying that the implementation of an instance
is fully held in its __dict__?  That would be simple enough, then...

Yet if you are right, this is exactly the functionality I was looking for.
What else, then?  I do agree that `self.__dict__ = some.__dict__' might look
tinily odd within an `__init__' function, at least until I get used to it :-)
