Howdy folks,
I have an LALR(1) grammar and lexer definition derived by machine
translation of the middle section of Matz's parse.y that compiles with
0 conflicts. However, I suspect that many of these conflicts are
masked by the compiler-compiler's overlapping tokens facility.
In fact, I have just tried an experiment where I "un-overlapped"
tLPAREN and tLPAREN_ARG (As well as '(' which is implicitly treated as
a token.) This resulted in 5 distinct shift-reduce conflicts and 27
reduce-reduce conflicts.
What progress have the grammarians made?
