Currently all productions in a grammar are required to match at least 1 token. This makes the grammar simpler to analyze, while losing only one single case of expressiveness -- it is impossible to declare a grammar accepting empty input.

The grammar format should be improved in some way to also allow grammars that accept an empty file or a file with just ignored tokens (such as comments and whitespace).
