BOUML - you gotta like it

I just got back to playing with BOUML - a really nice UML modeler and code generation tool. Earlier this year I successfuly managed to create state machine model and from it generate working C++ code to include in a framework testing part of the large embedded system functionality. This time I'm trying to employ BOUML to bring to life a library I was planning to release long time already (more details soon?). Anyway, working with BOUML is getting more and more interesting, and with each step it reveals more and more of its hidden gems (along with few flaws, naturaly).
