Not necessarily on the topic of the article itself, but I found this to be a good concrete example of how to think in Haskell (and functional programming in general?). I've just started learning by reading Learn You a Haskell. Even though there are plenty of examples in the book, so far, none of them are concrete. I found this article helps with the thought process of how to approach a problem in Haskell. The code snippets are accompanied with some clear explanations, and with some effort, I could figure out what the code does. If you're a new Haskeller, I would encourage you to take the time to understand what's going on.
