I don't know if it is a more elegant implementation, but I found something
like this for maps in the useful library a while back, called ordering-map:

I have been putting a few different varieties of sorted maps
Hi,
I want to sort a set/map according to an ordering given by a seq of
elements - e.g.
(def some-order [:u :a :e :i :o])
(def some-order-fn (order-fn some-order))
(sorted-set-by some-order-fn :a :e :i :o :u) ; --> #{:u :a :e :i :o}
This is what I came up with:
(defn order-fn [ks]
#(- (.inde
