-/// Unstabilized interface for defining syntax hl in lua.
-///
-/// This is not yet safe for general use, lua callbacks will need to
-/// be restricted, like textlock and probably other stuff.
-///
-/// The API on_line/nvim__put_attr is quite raw and not intended to be the
-/// final shape. Ideally this should operate on chunks larger than a single
-/// line to reduce interpreter overhead, and generate annotation objects
-/// (bufhl/virttext) on the fly but using the same representation.
