Custom stream extensions

[Arul Dhesiaseelan]

I was able to add extensions to my custom list implementation in earlier
builds.

  public MyStream<E> stream() {
    return new MyReferencePipeline<>(() -> Arrays.spliterator((E[])
this.toArray(), 0, this.size()), StreamOpFlag.IS_SIZED |
StreamOpFlag.IS_ORDERED);
  }


Now that, ReferencePipeline is made package local, this approach is no
longer possible.

It was extremely useful to extend some of these core classes outside the
package and toss in extensions with minimal coding. I assume this is not
encouraged?

Thanks,
