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 spec is definitely useful, though it doesn't really come out and say "this is the AST" it's more of a set of rules for identifying and parsing the components. AFAICT. Perhaps I missed an AST definition in my skim?
