This sounds like a way to essentially accomplish multiple inheritance without having to deal with the problems caused by actually using multiple inheritance. Mixins (in languages that have them) would seem to do much the same thing as well. Seems like a really good idea in this context; I will definitely keep this in mind whenever I'm faced with a huge, hairy, blobby object hierarchy.
