我正在解决4Clojure的问题.

我有一个Tic-Tac-Toe练习的工作解决方案,但我无法理解Darren的解决方案:

(fn [b]
  (some (fn [p] (first (keep #(if (apply = p %) p)
                         `(~@b                   ; <- What is that ` and ~@?
                           ~@(apply map list b)  ; 
                           ~(map get b [0 1 2])
                           ~(map get b [2 1 0])))))
     [:x :o]))
 ;b is a two-dimensional vector

`和〜@是什么意思？
