You're welcome! What idea, BTW?

It's easy to draw a graph by analyzing signatures of transitions. It's
not possible with switch_to<State>() because these calls can appear
anywhere in the on_process body. This is very important use case, IMO.
You can always define a state with a pointer to the state's data. This
is usually a good distinction especially if states hierarchy is used
to model inner and outer states. In this case, states hierarchy in often
not related to state's data hierarchy.
