Scala - Enumerations made easy... well... more or less

Enum.scala

// THIS IS Scala 2.11
// see: https://github.com/d6y/enumeration-examples
object Status {
  sealed abstract class enum(val id: Int, val name: String) extends Ordered[enum] {
    def compare(that: enum) = this.id - that.id
  }
  case object Starting extends enum(0, "Starting")
  case object Running  extends enum(1, "Running")
  case object Finished extends enum(2, "Finished")
  val values = Seq(Starting, Running, Finished)
}

//-------------------------------------------------------------------------------------------

// THIS IS SCALA 2.13
// see: https://github.com/scala/scala/pull/5352
@enum
sealed trait Toggle
case object ON  extends Toggle
case object OFF extends Toggle

//-------------------------------------------------------------------------------------------

// THIS IS enum using macros (quasiquotes)
// see: https://github.com/frgomes/poc-scalameta/blob/master/macros/src/main/scala/enum.scala

This is how you can use it:

def happyEnding(status: Status.enum): String =
  if(status == Status.Finished) "happy end" else "not yet"

I don't like the Status.enum bit. I suggest instead of the abstract class being an inner class of the object. Make it an actual class of the object. I'd also make a trait Enum and extend it but maybe that's just me
