Thanks, I looked at the operational package (since it seemed simpler). I see its interest when building sets of operations. I think I see how I could apply it to my current problem. I saw in the tutorial the sentence: "The ability to write multiple interpreters is also very useful for implementing games, specifically to account for both human and computer opponents as well as replaying a game from a script." So I'm supposed to write 2 functions, one interpretHuman (running in IO, and prompting the user), and one interpretAI (running in Identity)?
Are there examples of such games using operational?
