User blog comment:GamesFan2000/Another attempt at array notation.../@comment-35470197-20181114073145/@comment-37246647-20181114074017

1. Rule 1 is applied to that, so it equals {2, 2}.

2. Solved before I even saw this comment.

3. Also dealt with in Rule 7, it equals {2, 2, 1, 1, 1, 1, {2, 2, 2, 2}}.

The w typo was fixed before I saw this comment.
