Re: Re: non-exhaustive match warning for abstract type

To paraphrase, this is the one where sealedness doesn't extend to
subclasses, so you want to seal Abs:

scala> :pa
// Entering paste mode (ctrl-D to finish)

    object SealedMatch {
      sealed trait A
      sealed abstract class Abs extends A
      object B extends Abs
      object C extends Abs

      val value: A = ???

      value match {
        case B =>
        case C =>
      }

    }

// Exiting paste mode, now interpreting.

defined object SealedMatch
