(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).

Papers

Benchmarking seems not to be a main focus of any specific academic field, although the problem has been addressed by many different groups in CS.

Some papers I found interesting:

• http://www.sigmod.org/publications/sigmod-record/0806/p45.dewitt.pdf

Q: what book should i use to learn ML?

A: use several, and find the one that speaks to you.

the list below assumes you know a bit of math but
are not very mathematical, and are interested in learning
enough to be practical. that is, it is not at the
mathematical level of MIJ's alleged list
(cf. https://news.ycombinator.com/item?id=1055389 )

; it's a bit cumbersome to set up and there's the unfortunate need to ignore the tag
; in the individual methods, but this allows you to leave the interpretation of open 
; variants, well, *open* for extension by multimethod.

; dispatch off the first argument, which will be the tag
(defmethod command-multi (fn [tag & data] tag))

; the first argument to the *method* is still the tag
(defmulti command-multi :print [_ val] (println val))
(defmulti command-multi :read [_ fname] (slurp fname))
