The implementation has put a lot of focus on performance, currently it
parses 5000 syntax nodes (1200 SLOC) in ~2ms with Node.js. In contrast a
simple parser generated by Jison ( parses
the same code in ~110ms. I also benchmarked the Jison parser using my
own lexer, putting it at ~50ms.

Essential features that are currently missing but hopefully coming soon:
- Tolerant error handling
- Location tracking

I hope someone can find use of this.
