case object A

will translate to a term A with the flag Case:

package <empty> {
  final lazy module case <stable> <touched> val A: A$ = new A$()
  final module case <noinits> <touched> class A$ <method> <stable> <touched>()
     extends
   Object(), _root_.scala.Product, _root_.scala.Serializable { this: A.type =>}
}

The same for enums:

enum Color {
  case Red, Green, Blue
}

is transalted to

    case <stable> <static> <enum> <touched> val Red: Color =
      Color.$new(0, "Red")
    case <stable> <static> <enum> <touched> val Green: Color =
      Color.$new(1, "Green")
    case <stable> <static> <enum> <touched> val Blue: Color =
      Color.$new(2, "Blue")

There is no point having those assertions anyway. In the next PR Symbol_tree will return binds as well.
