I quickly scanned over the documentation, and didn't notice how they
have changed.
Are you able to provide an example?

Damn, maybe for the best though :)
Does this leave any opening for my previous feature requests?
i.e.
- Yielding
- Feeding more data (e.g. provide a callback for when lpeg reaches
the end of input)
I assume this means that the lpeg-jit has little hope of completion
now? (I'm so sad no one picked that up)
Thanks Roberto!
