Yes, that is the kind of thing I had been thinking of. Another is output routine programming: a function get_more_main_vertical_list_material_from_TeX would be quite handy in some applications, and yielding to TeX until the next pass would seem to make for some very straightforward and understandable programming.
you can already use a callback to collect material that is added to the vertical lists
I don't understand. What callback, and where is the material supposed to originate? What I was talking about is to let the normal TeX typesetting process come up with more material. Basically, not having to leave the current Lua context/variables/control structures for the sake of getting more material in the way "normal" for an output routine. -- David Kastrup
