Even though Factor is based on Forth, that's about where the similarities end. Factor was designed from the start as a stand-alone general purpose language, which is not what I'm looking for here; I'm fine with Lisp as a foundation. Object systems crammed into Forth will always be baffling, the fact that it's doable doesn't make it a good idea. I don't really buy into OOP at all; but i strongly prefer CLOS to alternatives, including Smalltalk; as it let's me reuse pieces of functionality without dealing with the rest. Using a fundamentalist language as a foundation will always come back to bite you from my experience. I prefer my foundations as general purpose as possible, which usually means C or Common Lisp.
