(apply has-map (apply concat (map (fn [b] [(apply hash-map (apply concat
(butlast b))) (val (last b))]) (list {9 5 9 9 7 8} {3 4 5 6 7 0}
{{3 4, 5 6} 0, {8 9, 9 5} 8}
I just added some noise!

Hey guys,
I'm having some trouble finding a nice way to perform a map
transformation I need. I need to transform this:
[ {:a 1 :b 2 :c 3} {:a 4 :b 5 :c 6} {:a 7 :b 8 :c 9} ]
into this:
{ {:a 1 :b 2} 3 {:a 4 :b 5} 6 {:a 7 :b 8} 9 }
I wanted to use map, but each f in map only returns one value,
Hi
(defn f [coll]
(into {} (for [{c :c :as m} coll] [(dissoc m :c) c])))
or
(defn f [coll]
(reduce (fn [r {c :c :as m}] (assoc r (dissoc m :c) c)) {} coll))
hth,
Christophe

(defn f

Untested.
