For non-orthogonal machines, saving the state is relatively easily done by 
inspecting the current state configuration with the public interface 
(state_machine<>.state_begin() & state_machine<>.state_end()). Loading is more 
cumbersome as you need to be able to go to the previously stored state after 
initiation. The only way to do this at the moment is to introduce special 
transitions.

Not really pretty and a lot of grunt work, I know, but that's the current state 
of affairs regarding serialization. IIRC, the serialization library still does 
not offer a way to serialize objects that have an overloaded operator new. This 
however would be an inevitable prerequisite for a decent statechart 
serialization implementation.

HTH,
