This post is a [literate
Haskell](https://gist.github.com/kisom/09e471e145bf1eca9124) file,
converted to org-mode with [Pandoc](http://pandoc.org).

Time to explore the `Applicative` type.

First, `fmap`:

;; -*-lisp-*-

;; Load swank.
;; *prefix-key* ; swank will kick this off
(ql:quickload :swank)
(ql:quickload :manifest)

(defvar *manifest-url*
  (manifest:start))

ATTRS{idVendor}=="5332", ATTRS{idProduct}=="1300", ACTION=="add", SUBSYSTEM=="usb", ATTR{power/control}="on"

kisom

#!/bin/sh
# convert Nikon NEF RAW images to FITS.
#
# depends on dcraw and imagemagick:
#     apt-get install dcraw imagemagick

IMAGE_LIST="$1"

if [ -z "$IMAGE_LIST" ]
then

kisom

(defun count-macroexpansions (form)
  (labels ((count-expansions (form n)
	     (multiple-value-bind
		   (expansion expanded)
		 (macroexpand-1 form)
	       (if expanded
		   (count-expansions expansion (+ n 1))
		   n))))
    (count-expansions form 0)))

Purity is a useful construct that forces programmers to consider that the
environment that they are operating in is unclean, and this introduces
barriers to formally defining the behaviour of the system comprising
the program and its environment.

This file is a [literate Haskell
file](https://gist.github.com/kisom/3863f17636d99b4f8401) run through
[pandoc](http://johnmacfarlane.net/pandoc/) to produce a Markdown
post. There might be a few glitches as I'm still developing a workflow
in this style.

produce markdown).

It seems customary in the Haskell space to write an introduction to
monads; my attempt in this exposition is not to outdo anyone else, but
to make the topic clear enough that I can write about it. My hope is
that by doing so, it becomes more clear to me.
