[boost] boost [msm] deferring event by base type.

24 Jun 2010

      I try to use the following code

struct base {};
struct event1 : public base {};

struct MyState1 : public msm::front::state<>
{
   typedef mpl::vector<base> deferred_events;
};

than MySm.process_event(event1());

when state machine in MyState1 causes that event gets dispatched and
not deferred the same code works if I replace

   typedef mpl::vector<base> deferred_events;

with

  typedef mpl::vector<event1> deferred_events;

than it works fine and event1 is deferred in MyState1;

It would be nice to able to defer event by it's base types it would
make code maintenance easier not have to declare all events one by one
for deferring.
