;; 1: normal funtion calls
(attach-events (display-board! (create-board 10)))

;; 1.5: added by popular demand :p
(attach-events 
  (display-board! 
    (create-board 10)))

;; 2: "chain"
(-> 10
    create-board
    display-board!
    attach-events)

;; 3: for some reason I don't think "10" is the start of the chain, the created board is.
(-> (create-board 10)
    display-board!
    attach-events)

;; 4: overkill?
(let [run-game (comp attach-events display-board! create-board)]
  (run-game 10))
