(defn compress [l]
(let [paired (partition 2 1 (conj (seq l) nil))]
(map #(fnext %) (filter (fn [[v1 v2]] (not= v1 v2)) paired))))

Same but threaded:

(defn compress [l]
(->>
(conj (seq l) nil)
(partition 2 1)
(filter (fn [[v1 v2]] (not= v1 v2)))
(map #(fnext %))))

It doesn't quite get you the arity, but it will "spread" the arguments for you. Mark What about (apply func ‘(1 2 3))?

It doesn’t quite get you the arity, but it will “spread” the arguments for you.

I really want to have a look at your Clojure solutions but I can't bare to have the solutions uncovered before I take a crack at the problems myself.
