[Pharo-project] PetitParser + Amber

Hi Göran, Quick question: during your work on Amber, did you find any particularly slow parts of PetitParser? Or, rephrased: while a hand-written parser is pretty much guaranteed to run faster than PetitParser (or any general parser generator, I reckon), are there any parts of PetitParser that leap out as being ripe for optimisation? Thanks, frank
