spec2不能在多spec中将fn作为retag使用

Question

请注意，这特别是一个与spec-alpha2相关的问题

我们将使用教程中的多spec示例

(spec2/def :event/type keyword?)
(spec2/def :event/timestamp int?)
(spec2/def :search/url string?)
(spec2/def :error/message string?)
(spec2/def :error/code int?)

(defmulti event-type :event/type)
(defmethod event-type :event/search [_]
  (spec2/keys :req [:event/type :event/timestamp :search/url]))
(defmethod event-type :event/error [_]
  (spec2/keys :req [:event/type :event/timestamp :error/message :error/code]))

(spec2/def :event/event (spec2/multi-spec event-type :event/type))
;;  ⇒ works as expected

(spec2/def :event/event (spec2/multi-spec event-type (fn [val tag] (assoc val :event/type tag))))
;; throws no impl of conform* for PersistentList

;; test case
(gen/sample (spec2/gen :event/event))

实质上，spec2还不能处理retag函数，这导致无法对简单映射以外的任何东西进行spec，遗憾的是。

是的，我们还在思考如何与符号spec相关的解决方案。
