> Please review this patch that:
> 1. Implemented `forEach` to optimize for 1 or 2 element collections.
> 2. Implemented `spliterator` to optimize for a single element.
>
> The default implementations for multiple-element immutable collections are fine as-is, specializing implementation doesn't provide much benefit.
