What you just said is this new thing isn't as good, and probably never will be, but you imply we should use it, even though the current tools are better.

See my complaint? If they are going to introduce a new tool, it must be better than the current tool. It's not and it's worse and not as mature.

I didn't say you should use it, nor would I. Only that it isn't pointless/futile to attempt. No tool will be as mature as bison or what have you until it has also been battle tested for 25+ years, but 25 years ago bison was also new and upcoming.

Not to mention that this is not even really a parser generator like bison or yacc... it's a combinator library. It's an entirely different way to write a parser. It's like me saying Python shouldn't exist because I know how to write C.

This one may not be that good. But any Packrat-based library is definitely much better than anything Yacc can offer.
