`racket' re-exports `racket/base' for syntax, while `racket/base' doesn't export anything for syntax. It's common to have #lang racket/base (require (for-syntax racket/base)) as in #lang racket/base (require (for-syntax racket/base)) (define-for-syntax aaa (string-append "x" "y" "z")) _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
