      You didn't read the post... cmp removal is a bad thing, and it 
does not need to,  and should not have to  happen.

     Wrong... one of the reasons for OOP in the first place ( OOA&D ) is 
to ensure that BAD THINGS DO NOT HAPPEN.  Code reuse and stability are 
key... and OOA&D helps to make sure that works.

     You need to read Grady Booch... and study a little OOP design 
either using SmallTalk, or C++, to get an appreciation maybe for what is 
at stake here. Yes, Python OOP is optional for the client perspective. 
But if chosen, OOP must WORK as expected by the OOP community if the 
language is touted as being able to support OOP, which also implies 
support for the spirit of OOA&D.

      You may not have enough knowledge to understand what I'm talking 
about.  Forgive me.
