Can Either add a result consumer method

1. Can Either add a result consumer method.

 /**
   * Consume the given result. in either a success (represented by Right) or a failure (represented by Left)
   *
   * @param rightAction the consuming function for the success value
   * @param leftAction the consuming function for the failure value
   */
  void ifRightOrLeftRun(Consumer<R> rightAction, Consumer<L> leftAction);

Isn't it easier to do just peekLeft() followed by peek()?

.peekLeft(s -> System.out.println("Left: " + s))
.peek(s -> System.out.println("Right: " + s));
