Before we spend more time on this, I think we need to have at least a
plan for that. Perhaps we could should disallow cases that we can't
handle otherwise. But even that would need some analysis of which
practical cases we can and cannot handle, how we could extend support in
the future, etc.
In the meantime, I have committed parts of your gram.y changes that seem
to come up every time someone dusts off an assertions patch. Keep that
in mind when you rebase.
