The cascade is a good tool. it's the reason why elements look "right" by default when nested another element within the document. The application of multiple classes to an element has nothing to do with the "Cascade". Your classes should describe their meaning, not their appearance. CSS was created to abstract away the appearance. Sass makes CSS more "CSSy" in that respect. In the end, built-in browser support for a higher-order stylesheet syntax will be driven by increasingly complex cross-browser issues, over-the-wire transfer of complex stylesheets and rendering-time performance issues. It could be the case that a few simple extensions to CSS would enable css preprocessors to do their job better, I have some ideas about that and will post them eventually.
