I agree regarding subclassing, but I don't like polluting the local 
namespace with things like 'extractClasses' as they give no indication 
as to where they came from the in the code.  It is one thing to do 
'from types import *' -- the types are all fairly specific in their 
naming and function -- but entirely a different thing to stick in 
something like extractClasses.

So, I end up with this...

from AppKit import NibClassBuilder
from AppKit.NibClassBuilder import AutoBaseClass
...
NibClassBuilder.extractClasses( "MainMenu" )
class DeDatAppDelegate(AutoBaseClass, NSDraggingDestination):
     ....

... which I don't like either, but does eliminate the dotted 
subclassing.

It didn't work and the error message was not at all clear.
