Oops, you're right; I was thinking about something else. And I have
another mistake in my function too—I meant:
(defn transform-map [f a-map]
(into {} (map #(vector (key %) (f (val %))) a-map)))
It's unfortunate that it's not in any standard library yet. I've used
this function in every single Clojure program that I've written. Ah,
well.
