I like ANTLR 4's innovations, which are missing from the article. This paper introduces the ALL(*) parsing strategy that combines the simplicity, efficiency, and predictability of conventional top-down LL(k) parsers with the power of a GLR- like mechanism to make parsing decisions. The critical innovation is to move grammar analysis to parse-time, which lets ALL(*) handle any non-left-recursive context-free grammar. https://dl.acm.org/citation.cfm?id=2660202 https://dl.acm.org/citation.cfm?id=2660202
