Hi Andy On clojurescript.net
running this: [(= "ab" "ab") (= "ab" (str "a" "b")) (= :ab :ab) (= :ab (keyword (str "a" "b")))] output: [true true true true] running this: [(identical? "ab" "ab") (identical? "ab" (str "a" "b")) (identical? :ab :ab) (identical? :ab (keyword (str "a" "b")))] output: [true true true true] What am I supposed to see here...?
