Also, Maybe and Either are not implemented as monads. They are defined
using `data` like you suggest:
data Maybe a = Nothing | Just a
data Either a b = Left a | Right b
I find the Monad instance for Maybe and Either very useful. You can do things
like the following (which technically only uses the Applicative instance):
Prelude Control.Applicative (*3) $ (+2) $ Just 1
Just 9
Prelude Control.Applicative (*3) $ (+2) $ Nothing
Nothing
Prelude Control.Applicative

This sounds really intriguing. Since I'm temporarily not using xmonad, and
I'm sure others would like to see as well, could we get a screenshot?

scalar. Also, I currently have a macro for the three sizes of vector and the
three sizes of matrix. I'm not going to mess around with it for now.

Hello,
I've been working on an ffi library for the Assimp asset import library(
http://assimp.sourceforge.net). It should be useful for people doing
graphics in Haskell. I've been working on it so I can import models into a
ray-tracer I've been working on. My current progress is here:
