A call of an applyDynamicNamed results in a NoPosition error:

object X {
  val d = new D
  d.meth(value1 = 10, value2 = 100)
  d(value1 = 10)
}
import language.dynamics
class D extends Dynamic {
  def applyDynamicNamed(name: String)(value: (String, Any)*) = name
}

Compiled with scalac -Yrangepos -Xprint-pos -Xprint:typer -Ystop-after:typer x.scala:
