I wonder, if you spend so much time writing fine-grained UML, aren't you already sort of programming? If so, wouldn't that time be better spent with an actual programming language with all the ergonomics and features you need? It seems to me UML shouldn't be dealing with this fine-grained level of detail. It seems like a wasteful effort. Either design high-level, or get down to actual programming.
