I have a need to convert maps in the following ways:
Given a map with keyword keys, I need a map with uppercase string keys
- and vice versa.
{ :stuff 42 :like 13 :this 7 } = { STUFF 42 LIKE 13 THIS 7 }
I've come up with various functions to do this but so far they all
feel a bit clunky.

This also helps in avoiding the contrib dependency.
Good point. Thanx BG.

clojure.contrib.string/upper-case is a trivial wrapper over

static Java methods directly instead of writing trivial wrappers
