  // The parts of the type class pattern are:
  //
  //   1. the "type class" itself -- a trait with a single type parameter;
  //
  //   2. type class "instances" for each type we care about,
  //      each marked with the `implicit` keyword;
  //
  //   3. an "interface" to the type class -- one or more methods
