OK, so today I was looking at Writer monad, a very basic Monad.

In its essence, it's just a Monad that outputs (e.g. log) something,
The "Variation three: Output" Monad from the original Monads for functional programming, 92 paper is very lean:

type M a = (Output, a)
type Output = String

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

The Atom documentation is excellent. It's highly worth reading the flight manual.
