[Pyobjc-dev] Reusing code in ObjC mappings

[Bob I. <bo...@re...>]

I've noticed that it's rather frequent for both a class and instance 
method to have a near identical signature and a near identical 
mapping.. for example, initWithBytes:length: vs dataWithBytes:length:

The only difference is really in one line of code.. the class method 
will say:
         PyObjC_InitSuperCls(&super,
             PyObjCSelector_GetClass(method),
             PyObjCClass_GetClass(self));

and the instance method will say:
         PyObjC_InitSuper(&super,
             PyObjCSelector_GetClass(method),
             PyObjCObject_GetObject(self));

There has to be a better way than this, so that we don't have all this 
cut+paste code to maintain.  Ideas?
