Oh plenty bad. Think of brittle C applications where everyone is afraid to touch anything since it might break. Type systems might not help you code faster, but they do decrease the worry of changing things later. You have to basically find or create abstraction boundaries in the code, then lift out localized balls of cruft and replace them a piece at a time. Or put another way, I usually prefer to edit with emacs, but sometimes you have to just plan on editing with rm.
