clojure - Expanding macros in macros -

-

i have following macro :

(defmacro add-children [this children]   (map (fn [child] (list '.addchild child)) children))

and create following macro : 

(defmacro defgom [name & body]  (let [sym (gensym)]   `(let [~sym (model.)]      (add-children sym body)))))

considering model java class addchild function. expand defgom 

(let [*gensym* (model.)]   (.addchild *gensym* (first body))   (.addchild *gensym* (second body))   ...   (.addchild *gensym* (last body)))

when evaluated, add-children macro gives correct result (the list of .addchild). can't evaluate in defgom macro. "don't know how create iseq from: clojure.lang.symbol". tried ~ or ~@ (given add-children returns list), none worked.

how expand macro inside macro?

ps: know can function rather add-children macro, want know if it's possible macro.

just change last line to:

(add-children ~sym ~@body)
