Can you give me a Python code example of the type of delegation you want to have and implement? It would help me wrap my head around the points you are raising. Off the top of my head, it seems that you could do something with __getattr__ and/or __getattribute__ (new to Python 2.2), but we need to get more concrete on the nature and use of the delegation you desire. (Sorry if you already did this and I missed the msg on the list. If that's the case, just tell me.) -Chuck _______________________________________________ Webware-discuss mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/webware-discuss
