I've used that and it works great, very compact and efficient. An explicit data structure with states, transitions, etc. is easier to explain to others and to manipulate programmatically, tough.

If you need more sophisticated state machines, like hierarchical state machines / statecharts, you can check this:

(it's a very light weight implementation, we use it on microcontroller-based robots)
