This all looks very nice. Is it possible to use this scheme with
polymorphic states, as follows:

struct Active {};
struct Stopped : Active {};
struct Running : Active {};

struct EvStartStop {};
struct EvReset {};

struct Fsm
  Stopped operator()( Running, EvStartStop )
    return Stopped();

  Running operator()( Stopped, EvStartStop )
    return Running();

  Stopped operator()( Active, EvReset )
    return Stopped();

Note that the EvReset transition should be triggered when the state
machine currently resides in either Stopped *or* Running.
