Re-parse for unresolved conflict?

[DiscreteTom]

In LR(1) we only check the next grammar to resolve the conflict but sometimes it's not enough.

Maybe we can add something like re-parse to rollback the parser, just like re-lex?

This may impact the performance, consider add a new build option reParse: boolean.

However, after enabling re-parse and don't resolve conflicts, the parser will usually use the wrong grammar rule to reduce.
It's not recommended to implement this feature. Language developers should always be clear about those conflicts and how to resovle them correctly.

For those conflicts that can't be resolved by next grammar, developers can use a function as the resolver's accetper, which can use the lexer to get more following tokens to resolve the conflict.

  .resolveRR(
    reducerRule,
    anotherRule,
    {
      next: "*",
      accept: ({ lexer }) => {
        lexer.clone().lex();
        return true;
      },
    },
  );
