You underestimate the amount of effort that was spend on the 2.x  
PyTypeObject implementation :-). It is already possibly to extend the  
type struct in Python 2.3 and later (at least of heap allocated  
types). One example use of this is PyObjCClassObject in PyObjC.

This won't work in Python 2.2, the necessary machinery was added to  
the type implementation in 2.3.
