You're right, coupling has to be kept low. For performance reasons it can be more efficient to duplicate code but maintenance becomes a nightmare (well IMHO of course ;) It's always the big problem between perfs/maintenance/evolution:etc. I think there should be core classes available at all times like validation, algorithms ... which we know will be here because there are used by other classes.
