trait Cake extends Slice

// Minimization
trait Slice { self: Cake =>    // must have self type that extends `Slice`
  private[this] val bippy = () // must be private[this]
  locally(bippy)

// Originally reported bug:
trait Cake1 extends Slice1
trait Slice1 { self: Cake1 =>
  import java.lang.String // any import will do!
  val Tuple2(x, y) = ((1, 2))
}


// Nesting
trait Cake3 extends Outer.Slice3

// Minimization
object Outer {
  private[this] val bippy = ()
  trait Slice3 { self: Cake3 =>

  }
}
