Trying to build doc on the fly:

cljs.user=> (defn tt {:doc (str "A" "B")} [])
cljs.user=> java.lang.ClassCastException: clojure.lang.PersistentList cannot be cast to java.lang.CharSequence

Setting other attributes doesn't evaluate the code:

cljs.user=> (defn tt {:ddd (str "A" "B")} [])
cljs.user=> #'cljs.user/tt
cljs.user=> (:ddd (meta #'tt))
cljs.user=> (str "A" "B")
