I've thought of a FSM representing a simple handheld calculator. With the current SMC, the definition would be really cumbersome and difficult to build, because each button (digit) press would require a different event. It would be great to have a way to mitigate this problem, but I wonder if that's a good idea or not.

In this case, events should have some kind of optional payload, so the keypad_pressed event can produce an action consuming the payload of that event like in this:

	AwaitingInput 
	{
		OnDigitKeyPress[x]		AwaitingInput		AppendInput[x]
                ...
	}	

This way, upon the code generation stage, the code could pass the parameter x to the AppendInput action.

Anyways, building a FSM like this with the SMC is still complex, since pressing an operation key in the calculator will lead you to a different operation state depending on the key, and there may be lots of different operations :)

As I said, it's just a consideration. Maybe somebody could come up with a good approach to use case.

Thanks for reading :)
