As much as I like matklad's work here I disagree. You can't have docs is AST and stuff like list element start with minuses. First requirement want to nest and organize everything, second one relies on some "natural" (highly contextual) way to do it. What looks natural for list of strings will not be natural for lists of tables of lists of maping between location snippit and some text.
