在Clojure中嵌套宏

Question

考虑这个伪代码：

(defrc name
  "string"
    [a :A]
    [:div a])

如果defrc是一个宏，那将扩展到以下

(let [a (rum/react (atom :A))]
  (rum/defc name < rum/reactive []
    [:div a]))

朗姆酒/ defc本身就是一个宏。我想出了下面的代码：

(defmacro defrc
          [name subj bindings & body]
          (let [map-bindings# (apply array-map bindings)
                keys# (keys map-bindings#)
                vals# (vals map-bindings#)
                atomised-vals# (atom-map vals#)]
               `(let ~(vec (interleave keys# (map (fn [v] (list 'rum/react v)) (vals atomised-vals#))))
                     (rum/defc ~name < rum/reactive [] ~@body))))

哪个几乎有效：

(macroexpand-all '(defrc aname
       #_=>   "string"
       #_=>   [a :A]
       #_=>   [:div a]))
(let* [a (rum/react #object[clojure.lang.Atom 0x727ed2e6 {:status :ready, :val nil}])] (rum/defc aname clojure.core/< rum/reactive [] [:div a]))

但是在使用时会导致语法错误：

ERROR: Syntax error at (clojure.core/< rum.core/reactive [] [:div a])

这是因为内部宏没有被扩展吗？
