WebDespite the advances made by modern parsing strategies such as PEG, LL(*), GLR, and GLL, parsing is not a solved prob-lem. Existing approaches suffer from a number of weaknesses, including difficulties supporting side-effecting embedded ac-tions, slow and/or unpredictable performance, and counter-intuitive matching strategies.
