Dear Lazyweb/Twitterverse, Do you have a favourite Markdown AST? I am already looking at Pandoc's AST for inspiration, but other examples would be useful. Any programming language is fine, I am capable of consuming ideas from most genres. Thanks, D.

The CommonMark dingus produces and AST (in XML form) as well as rendered output, so could be a useful reference point.
