What Hacker News says
5 sourcesIt's a little bit more than just a cute intellectual puzzle. One could build an efficient EDN library based on that or very similar type. See Haskell's JSON library:

> though the Clojure expressions are a little leaner
Yes they are. The price is complete lack of type safety. And the benefit is an insignificantly small reduction in boilerplate code.

In Compiler Errors for HumansI'm a relative newbie when it comes to Haskell; I've found it's best to just get stuck in - pick a project and just go for it. Especially if you're doing real-world stuff, because you'll just get sick to your back teeth of yet another fibonacci tutorial. Once you get stuck-in you'll find yourself on the Hackage docs site a lot, click on the Source link on the top right of every page, you'll find gold in there.
A real world thing I did this week (which unfortunately is proprietary so I can't share), was a distributed configuration system for our cluster. It uses the RabbitMQ library[1][2] and Acid-state library[3] to have a per-node config-DB and uses RabbitMQ's guarantees for delivery of updates to the nodes. Messages are serialised using Aeson[4], the Haskell JSON library. I implemented a vector-clock versioning system on top of the

Acid-state store to allow the clients to do conflict resolution. It really was a joy to write (around 350 lines of code). The C# client less so, 1000s of lines of boilerplate.
I think there's something really impressive about haskell; I tend to have significantly more trust in the code I write because mostly I know the edge cases don't exist. 9 times out of 10 if your code compiles it will work. Although be prepared for the compiler to hate you when you first start. The beatings are worth it though.
