Scala's support for implicit parameters lets you do most everything you can with type classes. Plus, implicits have scope in Scala, so can choose which you wish to apply in a given context. With type classes the scope is global, so you're stuck with one implementation per type per project. Unfortunately, I couldn't find a specific paper on this, but I've seen a talk by Bruno Oliveira on the relationship between implicits and type classes.
