I've implemented this a couple times recently, probably the best version is here: https://github.com/samth/pycket/blob/master/pycket/pycket-lang/expand.rkt The short answer is that you want to use `read-accept-lang` to enable #lang, call `read-syntax` once on the port, and the call `expand` in a new namespace (probably created with `make-base-namespace`).
