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.

Yes, but only at the cost of making the current interface (and implementation) more complex (we'd need to have at least a separate exit() function, right?).

No. At the moment we're just talking about whether A1 is justified. Whether or not exit actions should use destructors is a separate question. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
