That's definitely what I'm doing and I don't like it either. I just
haven't worked out a better alternative yet. Some of the functions use
many parts of the game state, so for those it seems appropriate to
just pass the game rather than a large number of arguments extracted
from the game.
For other functions that don't use very many pars of game, maybe I
should use more parameters. For example,
(defn win? [game]
(let [snake (game :snake)
body (snake :body)]
(= (count body) (game :length-to-win))))
Would you recommend that I change it to this and make the caller pass
two parameters?
(defn win? [snake length-to-win]
(= (count (snake :body) (game length-to-win)))
