(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).

If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.

(ns default-maps
  "Maps with default values, similar to how you can specify default values and blocks to Ruby's Hash.

Examples:

user> (def b (assoc-default {:foo 34 :bar 34} (fn [_ k] (str k))))
#'user/b
user> (get b :foo-bar)
\":foo-bar\"
user> (def m (assoc-default {:foo 34 :bar 34} 343))
