      A reverse linked-list, as an enumeration in Dotty: enum Tsil[+T] { case Lin case Snoc(init: Tsil[T], last: T) }

      So enums are the new ADTs?

      because this one looks like what you'd normally do with a sealed trait / object / case class to me

      I'm just worried about the syntax that (judging by the sample) would only work inside an enum

      in particular, the lack of "object" and "class" next to "case" :P

      Though `case` already has two distinct uses. A third isn't such a stretch... ;)
