reducible collections, transducing ops and other fast things

Relies on the latest Clojure 1.7

;; lein
[ghadi/reducers "0.1.0"]

(require '[ghadi.reducers :as r])

reducible variants of core

• repeatedly
• iterate
• range

ops that use reduce/transduce as a base

• count
• some
• select-keys
• zipmap (uses iterators)

new ops

• any (aka find-first or search)

• yield-first (reduces until first truthy value. underlies some & any)

• transiterate

Takes an Iterable and a transducer and gives you back an Iterable. Like LazyTransformer but for Iterables. Useful with the zipmap impl in this ns.

(let [iter (.iterator (transiterate (comp (filter even?) (map str)) [1 2 3 4 5]))]
  (while (.hasNext iter)
  (println (.next iter))))
