Quick recap/commentary: Clojure transducers
(comment ; Fun with transducers, v2
;; Still haven't found a brief + approachable overview of Clojure 1.7's new
;; transducers in the particular way I would have preferred myself - so here goes:
;;;; Definitions
;; Looking at the `reduce` docstring, we can define a 'reducing-fn' as:
(fn reducing-fn ([]) ([accumulation next-input])) -> new-accumulation
;; (The `[]` arity is actually optional; it's only used when calling
;; `reduce` w/o an init-accumulator).
(require '[clojure.core.async :as a])
(def xform (comp (map inc)
(filter even?)
(dedupe)
(flatmap range)
(partition-all 3)
(partition-by #(< (apply + %) 7))
(flatmap flatten)
(random-sample 1.0)
