(s/form (s/multi-spec ...)) 返回包含非符号对象的列表

Question

我的理解是，预期 S/form 返回可以被传递给 eval 的符号列表。多规格（multi-spec）的表单不会这样行为，返回的重新标记（retag）作为评估的值（例如，一个函数实例）。

(defn retag [x v]
  (assoc (vec x) 0 v))

(defmulti command first)

(s/form (s/multi-spec command retag))
=> (clojure.spec.alpha/multi-spec 
    current.ns/command
    #object[current.ns$retag 0x708d0436 current.ns$retag@708d0436])

;; should be something like
=> (clojure.spec.alpha/multi-spec 
    current.ns/command 
    current.ns/retag)
