Scalaz's Validations are a fantastic way to handle error checking. We use them pervasively in Myna. The rest of Scalaz I have found less use for, but I think that's due to the domain. I imagine if we had more types of data they would be beneficial.

If you've just come to read the comments, be aware that this article is extracted from a more detailed work-in-progress https://github.com/jrwest/learn_you_a_scalaz If you have a serious interest in Scalaz you'll be better off reading that.

Orignal article's title is better. Scalaz is a library for Scala, not "Scala's Library". There's some good stuff in there but it's a completely optional third-party library.

relevant exercises from one of scalaz' authors

and the applicative functor and following chapters in Learn you a Haskell (it wasn't real easy to navigate scaladocs, source, etc. Some folks used to just hoogle and then look for the same-named scalaz method

and the scalac switches -explaintypes, -Ytyper-debug are kinda helpful.
