One of the coolest benefits of preprocessors is that they have easy-to-grok open source parsers that you can actually get into. By injecting yourself after the pre-CSS code has been parsed, you can have a data-centric view of your styles. You can use this information to reduce complexity, point out probable mistakes, or more interestingly, gather metrics, and implement real-time update mechanisms on the client side.
