After this, NUMERIC_CONSTANT and strings should parse only one way. There are 8 types of literals, and 24 valid (literal, TokenKind) pairs. This means adding 8 new named guards (or 24, if we want to assert the token). It seems fairly clear to me at this point that the guard names are unneccesary indirection: the guards are in fact coupled to the rule signature. (Also add the zero guard I forgot in the previous patch.) Differential Revision: https://reviews.llvm.org/D130066
