I would welcome such a contribution to Bison.

I don't think so, yet I have not really carefully think about
that.  Joel E. Denny had something somewhere, but I seriously
doubt that we could involve him in Bison nowadays, as his schedule
is tight.

This is a very non trivial change in Bison, which does require
expertise from the contributor.  It's probably not impossibly
hard to have something work, the tricky part is certainly making
it _fast_.
