@Embedded<Container> - container needs a type check

[allComputableThings]

In the documentation on the main page:

  case class BlogWithEmbeddedMessages(author: String, @EmbeddedSet messages: List[Message])
  val blogWithEmbeddedMessages = BlogWithEmbeddedMessages("John", List(...)

@EmbeddedSet need to be consistent with the messages type (which is a List).
