 The other reason things have been quiet is that we're heading towards
a major rewrite -- we need to make ObjC objects into not just Python
objects, but Python classes that are fully subclassable. There is a
way to do this now with Extension Classes: this is used in Zope and
the Boost C++ libraries, but it relies on a hack that may be changed --
this has been under discussion on the Python-Dev list -- there is
an initial implementation of the new method in the python-dev cvs
tree, but I haven't had a chance yet to download it and look at how
it differs from the old method. ( Since the plan is to reduce or
eliminate the difference between classes and objects and to make
built-in objects subclassable, it's possible that not much new will
have to be done to enable this feature. )

 Being able to subclass objective-c classes in Python (which thru
the bridge, will appear as objective-c classes to Cocoa ) will make
it much easier to do Cocoa programming in Python.
