we could do that. However, we don't have a plan to implement an `LR(1)` yet, we use `SLR(1)`. (though LR(1) is more powerful than SLR(1), the typical deterministic LR(1) parser cannot handle the C++ grammar, we need a "general" parser GLR which can be able to handle arbitrary context-free grammars).
