Debugging a turing-complete full-fledged programming language is the same as debugging markup? Interesting.<p>I thought the whole point of Sass, the topic of this discussion, was to introduce more powerful programming concepts to CSS?<p>So which is it, is CSS already as powerful a tool as a programming language thus making Sass completely useless, or does it lack the capabilities of a real programming language, thus making it much easier for designers to use with proficiency?
