OrderedEnum

Trait to be extended by enums whose values are ordered by declaration order. Ordering is derived from SourceInfo object, which is typically accepted as an implicit, e.g.

sealed abstract class MyOrderedEnum(implicit val sourceInfo: SourceInfo) extends OrderedEnum
object MyOrderedEnum {
  case object First extends MyOrderedEnum
  case object Second extends MyOrderedEnum
  case object Third extends MyOrderedEnum

  val values: List[MyOrderedEnum] = caseObjects
}

In the example above, values is guaranteed to return First, Second and Third objects in exactly that order.
