Hello Erik,
I think the CST stage is now slower than before. I assume this is due to the recent change to the Piraha parser. Are we currently using the final, optimized implementation, or is there still debug code that will be disable in time?
I asked the same question and (par for the answer is): it is at parsing it with both methods and then comparing so it must be strictly slower :) This also qualifies for "debug code" I guess.
Yours, Roland
