This one is a bit strange. Maybe we could force them in a simpler way.

Oh, I mechanically edited the code without realizing what it was used for.
I changed it to just reference the lists.
ScalaValueClasses() doesn't need to be initialized since it's not a lazy val, so I removed it. Let me know if I'm wrong.
