Sorry for my misunderstanding. I thought we want to keep all the keywords
that were defined in the Antlr3 and later if we want to use them, we do not
have to add them back case by case.
Among the items I added, some of them (e.g. ASC, DESC) needs to be in the
non-reserved list, since they are used the parser and were non-reserved before.
Should I only focus on those? What is the best way to do it? Please advise.
Thanks.
