I like your approach and will probably use it in one of my two
pyparsing projects. Unfortunately, my other projects has about
600 BNF productions, some of them non-trivial. Adding ErrStop to
at least 100 or 200 of them would clutter my code a lot and I'm
yet sure it even would give the desired result. For that grammar
I still hope for inclusion of LastParseLoc or sth. similar in
pyparsing :~)

Thanks Eike, Gre7g, and Paul!
