> What exactly is the use case for being able to contact a process that implements either gen_server or gen_fsm via a standard API? I've never come across a use case where processes of different "types" needed to be mixed. If you really, really have to have that, you could implement a common interface via the handle_info/2 callbacks.
You haven't met. I have.

I have never ever seen any _production_ code, which is better with
gen_fsm. Thanks to Fred for study examples, but they are study
Ulf told something about SDL, but I really don't know what is SDL.
I beleive that there may be situation, when gen_fsm is convenient. But
I ask only to show example of such code.
