      Empty refinements prevent unwanted widening when assigning singleton-typed values to a val: https://gist.github.com/milessabin/65fa0d4ef373781d3ab4 … #Scala

      @oxbow_lakes No, it's a feature. It's been consistent since 2.10.x when I first noticed it, possibly earlier. Made good use of in shapeless.

      @milessabin It's useful, yes, but like @oxbow_lakes I guess (hope?) accidental and not designed.

      @milessabin @oxbow_lakes And it conflicts with "If no refinement is given, the empty refinement is implicitly added" http://www.scala-lang.org/files/archive/spec/2.11/03-types.html#compound-types …

      @milessabin @Blaisorblade @oxbow_lakes Specs are for changing and documentation is for coming back to haunt you once you've changed the API.

      Loading seems to be taking a while.
