A CSS question. Is there a CSS selector that selects the last consecutive sibling? Perhaps using :not or other tricks?

An example: https://stackoverflow.com/questions/22582449/selecting-last-consecutive-sibling

I think I’d expect the following from a Ruby perspective: (map { \|x, y\| (+ x y) } '((1 4)(2 5)(3 6))) i.e. a list of 2-tuples vs. 2 separate lists

Someone just mentioned https://github.com/carp-lang/Carp in another Slack. Looks interesting.
