This is beautiful, really.

I hate to spoil the beauty of it with remarks, but I can't help it:
given that everything is done in Lua, I suppose, why does it require
LaTeX at all? Plain TeX users can definitely use that.

Also, I would love to read it all explained in a TUGboat paper, a wiki
article, or both. It weaves together TeXnics and typographic concern
in a wonderful way, and it would make a nice third part to Hans's
original papers. So I hope all readers of this list will sing along
with me: `Patrick, an article! Patrick, an article!' (French readers
shall *not* lengthen the `i' in `Patrick'.)

Best,
Paul
