- In grammar
specifications, separation between semantic rules (inside
{{ }}
) and precedence information.
- Semantic rules a la Bison with semantic arguments:
E -> E + T {{ "Sum($0,$2)"}};

experimental implementation...)
- The class Yappy allows dictonary arguments that can
specify the directories where parser tables are stored (suggestion
due to Guillaume Pothier)
