I read this and wondered why you care? Isn't it sufficient to return the new world state? You could use identical? as someone suggested but why bother? It sounds like the player should be able to keep bumping into the wall if they keep making the same move.
I am just curious why the problem is more than computing the new world state from the old world state + user input + world self actions. What logic depends on whether it changed? To redraw or not? I'm learning functional myself so I like to hear how others design their solutions.
