Claim strikes me as a bit premature given the amount of Yacc based code there is in the world busy producing away day in and day out. If the algorithm is what it is said to be and I've no reason to doubt that, then at some point we will all be blessed with a Yacc replacement. Since I've always found Yacc to be a PIA, I certainly won't miss the old regime, but since there is nothing to use at the moment, I'm going to hold off a bit...

I have found hand-written parsers to be easier to write and easier to maintain than parsers generated by Yacc or its descendants.

There's nothing to use? What about ANTLR?
