Taylan, Thanks, that's exactly what I meant by "motivation" in my first reply. (There was a recent, 6 months ago or so, thread on sandboxing in guile-user by the way.) Was Matt trying to prevent _access_ (inaccessible vs. read-only vs. read/write) to data? Or was he trying to prevent only _visibility_ (e.g. for hygeine)? I think we need to know more about "what" and "why" to answer his question, rather than just "how"--if that makes any sense. Does Racket [1] even _really_ achieve what he needs to do (_prevent_ access for example)? We don't even know if we don't understand the higher-level purpose. (Basa) [1] Disclaimer: I like Racket too--it is a great project. I just hate to see someone leave Guile because of a minor technicality.
