By laughinghan:

I'd love to use `'left'` and `'right'` instead of having to deal with these "alternate universes", but how? I feel like I'd hate both typing or reading `[0]` and `[1]`'s. Maybe `left` and `right` instead of `prev` and `next`, and `leftmost` and `rightmost` instead of `first`/`firstChild` and `last`/`lastChild`? Then it could just be `[dir]` and `[dir+'most']` or something.
