I believe Sage's statement was that all current #lang racket modules will continue to work exactly the same, which is true. Nothing changes unless a module decides to use #lang racket2, and modules will not have to know whether or not their dependencies are written in #lang racket, in #lang racket2, or in a mixture of both. Backwards compatibility for existing unchanged modules will be preserved. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
