One line definitely won't do it (if you care about code formatting :-)), 
at least not with any of the FSM libs I know. With Boost.Statechart I 
guess you could do in with 30, hugely depending on the exact semantics 
you require. The simplest from scratch implementation (doubly nested 
switch-case statement) wouldn't be much longer...
