Using ''sandbox as an argument to `namespace-require` to refer to a local module is something like passing 'x to `eval` to try to refer to a local variable `x`. The `namespace-require` procedure doesn't know where it's being called from, so it doesn't work. Try `quote-module-path`, which expands at compile time to effectively embed its context: #lang racket/base (require syntax/location) (module sandbox racket/base (provide #%app #%datum test) (define (test) (displayln 'test))) (parameterize ((current-namespace (make-base-empty-namespace))) (namespace-require (quote-module-path sandbox)) (eval '(test))) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
