title: Datatype-generic programming libraries for Scala
body: <p>I'm looking for a Scala library allowing for datatype-generic programming (like <a href="http://research.microsoft.com/en-us/um/people/simonpj/papers/hmap/" rel="noreferrer">Scrap Your Boilerplate</a>, for example). A list of libraries with appropriate links and short descriptions for each one would be a perfect answer.</p>
