MDX support

[Kamahl19]

What would it take to support an MDX format, basically a combination of TSX and MD? These 2 are mixed together without any indication of which line of code is which language.

I am not aware what kind of heuristics this format uses to distinguish the two languages, but yeah, this sounds like a very awkward file format to write a parser for. You'd probably want an outer parser that categorizes each line or block of lines as belonging to a given language, and then use mixed parsing to use the TS or Markdown parser for the appropriate lines.
