Awesome!

Several years ago I compiled the Lua interpreter into Emacs and added
functions for accessing each from the other.
It was just fun experimental software and is not supported or actively
developed and still has unresolved issues,
but might be of interest to you. This was before modules got added to Emacs.
You can check out the code here: https://github.com/mschuldt/luamacs
