Hi Hans,

just to say that I reproduced Henri's code just to have
a stable base for testing, that he contributed the code
in a tex.sx answer I linked to, and that I don't know
if he has time to devote to optimizing the code: the
question was about how to do things in various ways,
how to set up the \directlua etc..., or possibly 
with pythontex or whatever.

on a light note,
I dearly hope Henri does not optimize, or change 
implementation, because 
currently my own plain TeX approach to the same
question on tex.sx is competitive with it.

Best,

Jean-François
