[luatex] insert a string into node list?

Hi,

the first one is not that unusual...

No, but it's not annoying at all. See 

http://wiki.luatex.org/index.php/TeX_without_TeX

esp. at

http://wiki.luatex.org/index.php/TeX_without_TeX#And_what_about_real_content.3F

and for a real life function at

https://github.com/speedata/publisher/blob/develop/src/lua/publisher.lua function "mknodes", but this is currently in German only (its on my todo list to translate this!)
