Is it possible to apply this apporoach to the asynchronous_state_machine?
For some reasone, trying to do so in my program causes compiler error: "use of undefined type 'Active'". Probably, I've done something wrong, but I'd like to know if it should work theoretically, before I turn my code upside down :).
Thanks!
