I have a question about the lifetime of the state objects.

I have the impression that the state objects are created when then FSM 
is created and destroyed when it is destroyed.  Is this correct?

Thinking about my own FSM code, implemented ad-hoc, I have variables 
whose lifetime should correspond to the period spent in a particular 
state.  (Or, more generally, the period spent in a hierarchical group 
of states.)  It looks like I can get this only by using the enter/leave 
hooks and a pointer.  Is this correct?

Phil.
