parboiled2 [https://github.com/sirthias/parboiled2] offers pretty much everything the built-in parser combinators do, but with fewer bugs and vastly improved performance. Since both use PEG grammars, it should be straightforward to port over. parboiled2 is fast because it generates fast, stateful parsers using macros while only exposing a purely functional interface.
