How about using language directives when available, and trying to guess the language when not? And about the directives, what should they be? ',language' is what we used to use at the REPL, and I was about to write an email arguing for that, until I realized that there is one big advantage to using the same thing as Racket - we might actually share some languages. Specifically, if someone had a Scheme file that started with '#!lang r5rs', it's possible that Guile and Racket could both run that file without modification. That seems pretty cool. Mixing other languages could be scary though. Noah
