Robert, your help is much appreciated. I have been researching and 
trying to get a grasp at the topics at hand: mixins, enumerable, etc - 
and trying to keep an open mind to alternatives. Todays task is to get 
your suggestion up and running and play with it by writing a bunch of 
unit tests (a great way to learn btw). Me needs to become friends with 
stubs (stringio) and mocks (flexmock) ...

Cheers,


Martin
