Shameless plug, but you can try it already . It should give you an
idea of how it might be integrated. Feedback welcome.
Nyanga statically links with LPeg, and although the grammar syntax is
very similar to the 're.lua' module, it doesn't pass a string to
're.lua', but produces an LPeg grammar directly using the API.
