Duck-typing means that the only reliable way to assess whether two types are sufficiently compatible for some purpose is to consult the documentation -- you can't just look at the base class list. I think this should work both ways. It should be okay to *not* document autodict as being a subclass of dict, even if it happens to be implemented that way. I've adopted a convention like this in PyGUI, where I document the classes in terms of a conceptual interface hierarchy, without promising that they will be implemented that way.
