clojure.set/rename-keys

(clojure.set/rename-keys m kmap)

Answers m with each key of kmap it holds renamed to that key's value in kmap. Every key of kmap is dropped first, so two keys may swap. nil answers nil; a record stays one unless a declared field is renamed away. Reached also as alias/var or a referred bare rename-keys; works as a function value too.
