Quick draft of View-Presenter injection with the cake pattern

CakeMVPTest.scala

trait SomeView {
  def render(): Unit

  def init(): Unit
}

trait SomeViewComponent {
  this: SomePresenterComponent =>

  val someView: SomeView

  class SomeViewImpl extends SomeView {
    presenter.view = this

    def render() = Console.println("Rendering!")

    def init() = presenter.init()
  }
}

trait SomePresenterComponent {
  val presenter: SomePresenter

  class SomePresenter {
    var view: SomeView = _

    def init() = view.render()
  }
}
class ComponentRegistry extends SomePresenterComponent with SomeViewComponent {
  val presenter = new SomePresenter()
  val someView = new SomeViewImpl()
}

val view = new ComponentRegistry().someView
view.init()
