[Pythonmac-SIG] Getting None in KVC objectInKeyAtIndex_

[Ronald Oussoren]

A better way to define such accessors is like so:

     @objc.accessor
     def objectInFooAtIndex_(self, index):
        pass

This should deduce the right method signature based on the method  
name. I guess this needs better documentation :-(
