Two years back at the WoTUG conference, I presented a few
handwritten slides on combining OO and CSP.  These days, I
think the following:

- CSP is a very good form of object orientation
  (Peter Welch has already said this many times.)

- I think many OO practices are fundamentally not
  true OO.  I think CSP is true OO.
  
- Mixing CSP with bad OO practices is persuasive,
  but intrinsically wrong.

- I have (strong) doubts whether the direction John suggests
  is the right one at all.
