Indeed, the error messages could be improved in lots of ways -- I just took the reference implementation and improved it in the most obvious ways. I had hoped that things like the following would get better errors from `syntax-parse' automatically: -> (let-values) -> (let-values 3 4 5 6) -> (let-values (3 . 4) 3 4 5) But they didn't, unfortunately. I don't know if Ryan will change that ever. If there was something between `syntax-parser' and `define-simple-macro', that would be the right tool here. -- sam th sa...@ccs.neu.edu _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
