Hi all,
I have created an open for all project with ComplexCondition
as described in Andres Valloud's book "A Mentoring Course on Smalltalk".

http://www.squeaksource.com/ComplexCondition

This class will allow to write very intention-revealing code.
Have a look at the tests: a pearl of design IMHO.

Hope it helps
Bye
