What is the ctor of myDestination going to do with them? Where do these 
arguments come from? What did you do with them in the react function?

There are various ways: Have a variable in an outer state, have one in 
the FSM, use a transition action or avoid the problem altogether. What 
exactly the best one is really depends on the source of your problem.
