Pablo,

>Thank you Sergey. I am still in apprentice mode, and am reading Advanced OOP, The Fundamentals..., The Hacker's Guide 7..., and some other resources. Upon reviewing Markus Egger's section on instance programming and pseudo subclassing, I noticed that those sections apply to subclassed base classes, that's when I thought about relating those sections of the book to some "homework" practice on my part.
