Ok, so your proposal is about typing symbols, which is already
supported by Bison.

So far, I don't see the need to add more attributes.

Rewrite.  It's not about refactoring, it's about writing it from
scratch.  The lack of support for variants comes from the fact that
the core of glr.cc is glr.c, in a C style that does not respect
C++ object lifetime.  That's why it must be first rewritten in C++.

I have received your request to be part of the Savannah, thanks for
your interest!  However, to contribute to Bison that's not necessary.
What is really needed first is signing the FSF disclaimers.

But we should also first see how you can help.  Let's give Valentin
some time to answer first.

Cheers!
