I have been coming to the same conclusion. It seemed like a nice idea to begin with but as they say ... the devil is in the details. If you haven't already figured it out ... I like simple. At first it was simple ... but no longer.

Which is exactly what I am doing and is why I am searching for the best data structure on which to base my classes. Not using codes at all is as simple as it gets and I am surely attracted to that concept. However, that just seems to go against all my years of development instincts. On the other hand it seems tha only systems with huge amounts of data would be noticeably affected by this concept. I think I am going to try it.
