The current sweet-expression reference implementation uses "_" in a number of function definitions. However, elsewhere in the code (and in most code), a "-" is used in symbols. That's a weird inconsistency, and I intend to switch all the "_" in symbols to "-". The "_" is just an artifact, actually. I used ANTLR to do rigorous grammar-checking of the BNF... and ANTLR only allows "_" in names, not "-". But it makes the reference implementation look funny; there's no reason the Scheme implementation can't use "-" instead. I can't imagine anyone complaining about this superficial change. But please speak up quickly if you object!! --- David A. Wheeler
