Codebases were littered with (vec (map ...)) and (reduce (fn [acc [k v]] ...)) patterns which are nothing but noise. This change removes the need for that, makes the intention clearer and in the case of reduce-kv removes the need for lambdas in some cases (where it was used only for destructuring).
