I use this sort of thing in Tcl ( for path-dependent reasons ) A Whole Lot. You can have arrays, indexed by state, and use the "eval" operator to "eval $fsm($state)" fsm is an array of strings, indexed by whatever. I have made dynamic state machine generators this way, although it gets kinda disorienting. The tactical advantage to Tcl (for me) is that it has serial ports and sockets as first-class objects with essentially identical semantics. I work in the embedded space, and this seems 1) unusual and 2) a very nice thing to have to write comprehensive test rigs. I rather like it better because it's all in the "string" & "list" domain rather than the lambda domain. I really should try this in Lisp just to see how wierd it gets.
