Ah, now I get it. You want to be able to use 'import Carbon.Carbon; 
print Carbon.Carbon.TrackWindowProxyFromExistingDrag' to find 
information about 'TrackWindowProxyFromExistingDrag' as defined in the 
Carbon/Carbon.h header.

If T is an extension type (such as Carbon.Win.Window) the following 
snippet will add the methods of the class to the global namespace:

MethodWrapperType = type(list.pop)

for name in dir(T):
     o = getattr(T, name)
     if isinstance(o, MethodWrapperType):
         globals()[name] = o

BTW. I guess that if the big namespace exists people will use it for 
day to day use, if only because of the way the Apple documentation is 
structured.
