Hit! You sunk my Adjunction!
View Battleship.lhs
Today we'll be looking into Kmett's
[adjunctions](http://hackage.haskell.org/package/adjunctions) library,
particularly the meat of the library in Data.Functor.Adjunction.
This post is a literate haskell file, which means you can load it right up in
ghci and play around with it! Like any good haskell file we need half a dozen
language pragmas and imports before we get started.

Programming Achievements: How to Level Up as a Developer

  1. Select a particular experience to pursue.
  2. Pursue that experience to completion. (Achievement unlocked!)
  3. Reflect on that experience. Really soak it in. Maybe a blog post would be in order?
  4. Return to Step 1, this time selecting a new experience.

This gist is a fork of the gist from this blog post.

You can’t perform that action at this time.
