Method references not counted as covered unless called

[dsilvasc]

When you pass a method reference to another method, scoverage marks the reference itself as uncovered until you exercise it:

case class Route(path: String, handle: Int => Int)

class Server(routes: Seq[Route]) // { ... }

class Service {
  def inc(n: Int) = n + 1
  def dec(n: Int) = n - 1
}

object Module {
  val service = new Service
  val routes = Seq(
    Route("inc", service.inc),
    Route("dec", service.dec))
  val server = new Server(routes)
}

In the example above, service.inc and service.dec are marked as uncovered. Is this related to eta expansion?
