Wrong example of proteted

wrong protected

class Node {
  def eval(other: Node): Unit = other.protected_method(this)

  protected def protected_method(other: Node) = other
}

class NodeFake(node: Node) extends Node {
  override def eval(other: Node): Unit = {
    println("pre")
    println(this == other.protected_method(this))
    println("pre")
  }
}

new NodeFake(new Node()).eval(new Node())
