I love the idea! This makes a lot more sense than writing Formatters and repeating code everywhere. I'll play with this later today. Thanks!

You're welcome! The idea is to simplify writing basic Reads/Writes for simple Scala structures. In this way, you can focus on writing more complex JSON validation/transformation when you need it... For JSON coast-to-coast design that I introduced in previous article, this is quite useful!
