Castle Boo - II

I am trying to write a small project to understand both Boo and Castle Project.
I have already written my first two small rules here.
Today I try to solve the question of inheritance. It may seem silly to ask a question wheather EnteredBill should inherit from Task if EnteredBill is Task in my concept, but as I have written before, I like the generics and it is not yet completelly usable in Boo (read here).


I will update this when I find the suitable way.
