This gist and its comments are a way of working through an exercise problem found in Chapter 15 of the Haskell Book.

Here's the code from the exercise. Our job is to implement the mempty and mappend functions, which are presented here as undefined:

module Chap15Ex where
import Data.Monoid

newtype Mem s a =
 Mem {
