Semantic highlighting: infix notation for extractors

Extractors aren't correctly highlighted when they occur in infix notation - instead they are shown in colors of operators or of something other (couldn't identify it):

object Test extends App {

  val x :: y = 1 :: 2 :: Nil // wrong
  val C(a, b) = N C 2 C 1 // correct
  val c C d = N C 2 C 1 // wrong
}

trait L[+A] {
  def C[B >: A](b: B): L[B] = new C(b, this)
}
case class C[A](h: A, t: L[A]) extends L[A]
case object N extends L[Nothing]

In the first line, the :: is marked as an operator.
In the second line, the first C is marked as a case class.
In the third line, the first C is marked as an 'others'.

@sschaef, I'm not following what would be your expectation? To have all of them marked as a case class, or class?

My expectation is that all of them are marked as case classes, because that is what they are in the example. If someone writes an unapply method manually it should be shown as a normal class.
