FYI this works as you expect if GeneralTypeOfObject is an old-style class (i.e. does not inherit from object). If this feature is so more important than all those that come with new-style classes, you have control over the involved classes and don't care about Python 3.x (where old-style classes are gone), you may choose to downgrade GeneralTypeOfObject to old-style.
