That's probably true.  I would certainly like to eventually lose the
tentative diagnostic stuff.  There's no abstract reason why we should
be issuing error messages during tentative parsing.

Well, I didn't find the current scheme difficult -- but saving the
copies would be great.  And I'd certainly like to lose the source
position information that I'm current saving.

Your interface sounds reasonable to me, and it would indeed simplify
and improve the efficiency of the C++ parser code.
