Hi Markus,

Jan Kurs and me are now working on some PetitParser stuff. If we succeed
then PetitParser-based parser would be as fast as current hand-written
RBParser. We're at the beginning but preliminary benchmarks are very
promising.

Error recovery and incremental reparsing are in the queue (if we
find a time :-)
