> FixScript allows any syntax changes and it's done as a preprocessing step.<p>This kind of separation bothers me a lot in Markdown for static site generation. You typically use Jinja-like templating on top of regular Markdown, and there's a preprocessing step for the templating. This is sometimes limiting in my opinion, as there is a fixed order of operations (preprocessing, then Markdown parsing/rendering). And the two styles of markup are very different. reStructuredText / Sphinxdoc is nicer in that regard because there is a consistent syntax that is arbitrarily extensible.<p>Can you show some examples of FixScript's extensibility, ideally showing that it's better than a C preprocessor?
