I know there's a smiley, but you're not doing your credibility any
favors with that statement. It makes me wonder how many other
decisions in the design have such a flimsy foundation.

If you want to convince _me_ (I'm not saying that's important or
anything), you're going to have to make the case for why an FSM object
should make transitions (or state changes, if you like) when it is
destroyed. To me it seems like there are very obvious use cases
supporting the argument that it should *not* happen. Furthermore, it
seems as though, if you want that behavior, it's trivial to get it by
wrapping the FSM in a derived class whose destructor finalizes the
state machine.
