Great ! In Ocamlwizard, we've patched an ocaml parser (3.10.2) which recovers
on errors located at the end of \ffile (using the EOF token). We've also consider using the error token but it's more difficult (because of ambiguities). 

Since dypgen generates multiple parse trees, It could be easier to implement this feature. I hope I'll have time to try it.
