this was an idea i had: https://github.com/non/scala.github.com/pull/1#issuecomment-331061749 … (we haven't put anything like this in the sip yet)

And if so, where does the type fit in the type hierarchy? Could you wrap a case class extending a sealed trait, say?
-
Would be interesting also if opaque types had corresponding singleton literal subtypes. :)

Ah, I missed that. I assumed so. The type-hierarchy question is important. Seems like there may be some challenges with runtime type tests.
