In CLJ-1894 I proposed a patch to change clojure.walk/stringify-keys to include namespace if keywords use namespaces. I made a wrong assumption about backwards compatibility of that change, however I still think the behaviour is not exactly what it should be.
Interesting thing Alex Miller pointed out in his comment to CLJ-1894 is that stringify-keys and keywordize-keys are essentially the same function with a different transformation. I think having one function which does a deep transformation of map keys using a transformation supplied by user is a good idea and it could be used to simplify some Clojure libraries.
- add clojure.walk/transform-keys to walk a map and transform all keys
- use transform-keys in clojure.walk/stringify-keys & clojure.walk/keywordize-keys
