Treat parse conflicts as errors in grammar compilation
...
For now, only reduce/reduce conflicts w/ no tie-breaking precedence
are treated as errors. The rest are dropped, because shift/reduce
conflicts are currently very common because we don't have a way
of specifying associativity along w/ precedence.
