is this a known diff between Clojure and ClojureScript?

(defn f
  ([x] 1)
  ([x y] 2))

(with-redefs [f (fn [] 1)]
  (f))

Clojure doesn't warn about arity mismatches in general

I bet the problem here is that the CLJS analyzer doesn't account for dynamic redefs

@roman01la yes

@borkdude the compiler cannot see dynamic stuff - so there's nothing to do
