ok, starting to make sense now
...
Putting together two resources:
https://lucasklassmann.com/blog/2019-02-02-how-to-embeddeding-lua-in-c/#exposing-a-simple-variable
https://www.lua.org/manual/5.3/manual.html , section 2.1, "Values and Types", particularly the description of light user data.
And lo, I see lua_pushlightuserdata in lapi.c

Lua's power may come from extensibility, but the indirections are
currently in the way

trying to make sense of how bindings are created
...
lua_State contains these StkId fields (stack, stack_last, base, top)
that expand to a pointer of a struct containing a Lua value and an int.
Unclear how it's used, or how you build a stack out of it.

Currently it works with stock Lua and lcurses. Our job now is to build
in the bindings to make it work here.

print's newline now returns to column 0
...
At this point I'm done making this repo ncurses-ready. Remaining files
that allude to stdin/stdout/stderr:
lauxlib.c - unclear how these primitives should work; may kill them
ldblib.c - unclear what debug experience should be
liolib.c - might kill or simulate these
luac.c - let the compiler continue to be a terminal program

ncurses I/O in lua.c

Currently working:

Print's newline doesn't return to column 0 yet.
Ctrl-d no longer works. Ctrl-c exits cleanly.
