Re: [racket-users] Running a program in multiple languages at once

Hey all, I ended up figuring this out. The solution was essentially to make a reader that looked like this: (define (read-syntax input-port) (let ([copy1 (copy input-port)] [copy2 (copy input-port)]) (with-syntax ([mod1 (Lang1-read-syntax copy1)] [mod2
