Count me among them. The #: is more consistent and typing one more character doesn't bother me. > > > * Multiple-value LHS in "let" forms I agree with that one. Regarding this I also have a question. Sometimes I just need one of multiple values, but this always bothers me somewhat. Take for example (let-values (([a b c] (values 1 2 3))) (computation-with a)) Are the spurious bindings to b and c optimized away if they aren't used? Is this even possible in general? If not, I'd like to see effective primitives like take-nth-value, take-first, take-second, etc. which discard the other values for sure. This would also open the door to some high-level optimizations, albeit presumably quite complicated ones. Best, Erich ____________________ Racket Users list: http://lists.racket-lang.org/users
