Did you iterate to a FSM solution, from many nested conditions, or use it right from the start? I'm fighting the urge to write any FSM without having the absolute certainty that it is needed. There seems no other way than by refactoring to an FSM.
I have started from already existing FSM libs (which did not fit well) and after couple of experiments understood that creating own custom FSM processor is a no-brainer with clojure/core.match
