algo.generic has a functor implementation for regular maps which you could
already use, if your maps have uniform depth:
(fmap (partial fmap inc) {:a {:x 1} :b {:y 2}}) ---> {:a {:x 2} :b {:y 3}}
if you want to use that fmap (or, I'd think, the fmaps provided by either
morph or fluokitten) with uneven depths, you'd have to wrap them in a
defrecord or deftype, I'd expect.
