Thanks. I did work with ZClasses and PythonMethods - I wasn't gone 
that long. I couldn't see how ZPatterns are actually implemented, 
regardless of what tools are used - but I'm getting it slowly, mostly 
by collecting a lot of tips from posts in the list over the past few 
months. ZPatterns looks great and definitely worth the learning curve 
- I'm off to buy Coad's book so I can do it right.
