Type classes are an important combination of several Scala language features: traits, generics aka parametric polymorphism, implicits, scopes, annotations - which can be received scary even without combining.

The Scala standard library and most third-party libraries make extensive use of this interesting mix, so it’s a good idea to try it out ourselfs.
