Not particularly enamored with the results there. Poorly-done, abstraction actively gets in the way of combination. At some point, everyone has to agree on the same abstraction if they're gonna work together; enough of CSS has been widely implemented to allow folks to build on that, while plenty of other, richer, more powerful abstractions predate it, but were never widely agreed upon.
