Hello, Sérgio!

It's good you're on this mailing list! Thank you for taking the time to
write an answer.

I did not intend to criticize your work. Rather, I posted some questions
that your work inspired.

Why do we search for PEG+Left when the set is so theoretically undefined?

We know this:

   - LL < PEG < LR < CF (yes?_
   - PEG < PEG+LEFT_X

What we don't know is:

   - PEG+LEFT_X ? LR

In my opinion, we also don't know why we care.

In the end, I may just be clearing my mind before I remove left-recursive
grammars from Grako, just so there are no wrong expectations about what's
possible.

Cheers,
