Case Class Mashalling - Compile Error when defining CC in Block Scope

[frne]

Is it intentional, that case classes must be defined at top level and cannot be inside other scope?

Works:

class CaseClassSpec extends FlatSpec with Matchers {

  @label("example")
  case class Example(@id id: Option[Int],
                     longValue: Long,
                     stringValue: Option[String])

  "Gremlin" should "be able to Marshall case-classes" in {

    val graph = TinkerGraph.open.asScala
    val example = Example(None, Long.MaxValue, Some("optional value"))
    val v = graph + example
    v.toCC[Example] // equal to `example`, but with id set

    // find all vertices with the label of the case class `Example`
    graph.V.hasLabel[Example]

    // modify the vertex like a case class
    v.updateAs[Example](_.copy(longValue = 0L))
  }
}

Does not work:

class CaseClassSpec extends FlatSpec with Matchers {

  "Gremlin" should "be able to Marshall case-classes" in {

    @label("example")
    case class Example(@id id: Option[Int],
                       longValue: Long,
                       stringValue: Option[String])

    val graph = TinkerGraph.open.asScala
    val example = Example(None, Long.MaxValue, Some("optional value"))
    val v = graph + example
    v.toCC[Example] // equal to `example`, but with id set

    // find all vertices with the label of the case class `Example`
    graph.V.hasLabel[Example]

    // modify the vertex like a case class
    v.updateAs[Example](_.copy(longValue = 0L))
  }
}

Error:

Error:(19, 19) not found: value <none>
    val v = graph + example

It's not a requirement to work, but maybe the error could be a bit cleaner, or stated in the readme...

it's a restriction of black box macros I believe..
