We first tried to figure out what was happening, but we didn't succeed and spent a lot of time on it. Then Nicolas decided to go "native" on the problem. I rewrote ChunkParser - because it was also in PP and was also going into endless chewing. Nicolas used PEGjs to produce a new parser.
Note that the AST and code emitting etc is still in Amber.
And oh, I only rewrote the ChunkParser in Amber - not in raw js. And in fact, it came out simpler I would say - but chunk format is not that complicated (although a bit messy to get right). Btw, Nicolas just checked out an old Jtalk to see how much difference the "changed lookup" made - and for tinyBench it only took a ... 20% hit or something. Not a magnitude thing. (this is referring to what Lukas wrote in another post) We might need to investigate why the endless chewing came about though - because it indicates some kind of bug somewhere I think, probably in Amber itself, or in the PP port. regards, Göran
