I personally don't really understand the point of such a feature,
because yaxx is LALR.  So your grammar is tortured, it is not faithful
to what you actually have in mind.  Besides, quite often the grammar
one has in mind is EBNF like, with repetitions that you wish to see as
"real" lists rather that cons-lists.

I use SDF/SGLR regularly, and they have this feature, but they run a
GLR engine, and it makes much more sense: the grammar your tool eats
is the grammar you want to work on.

Now, since Bison has GLR, it might make more sense than before, yet, I
am still not convinced.

Can you explain what was nice in using Yaxx?
