Type classes

Ideas for exercises:

  • Define a new XmlEncoder type class with a single toXml method.
  • In the companion object, provide a constructor method with the following signature: def instance[A](f: A => String): XmlEncoder[A]
  • In the syntax object, provide an implicit class which will let us call a toXml method on any instance of a class which has an XmlEncoder instance.
