!^ and ^ are inconsistent (or last-child needs its own combinator)

[Inviz]

Sorry for messy formatting.

[1:03pm] Inviz: Do you guys think '^' and '!^' combinators in slick (first & last child) are inconsistent compared to other combinators?
[1:03pm] Inviz: Other combinators like ' ', '+', '~' can be inverted to match from child to parent
[1:05pm] Inviz: while inverting ^ and !^ does not reverse the matching logic, it reverses the first-last child semantic
[1:08pm] Inviz: Slick.find(ul, 'li') //li Slick.find(li, Slick.parse('li').reverse()) //ul
[1:08pm] Inviz: that works transitively for all combinators
[1:09pm] Inviz: ^ li reverses to li !^ *
[1:09pm] Inviz: and grabs last child of LI
[1:10pm] Inviz: the correct way here would be to make !^ return parent IF current node is first node
[1:10pm] Inviz: but then last-child combinator needs its own combinator
