   I am looking for a scheme allowing to write DCG rules abble to process
   efficiently syntax errors:
     . to display relevant error messages
     . to re-establish (eventually) the parsing process.

   I found the naive approach - introducing 'catch-all' grammar rules -
   not enough precise. Being more deterministic, on the other hand,
   decreases the declarative aspect of the rules and leads consequently
   to a more tedious overall design ...

   Thank you
