I think it might be worth giving non-normative examples of output for the various procedures. This shouldn't be construed as providing some kind of canonical list of OS types (for instance), but it's not a lot of use if Rhinoceros Scheme returns "Windows" as a result of (os-type) and Diplodocus Scheme returns "win32". Even just specifying "windows", "linux", "macosx" as potentially valid results for OS-TYPE will improve the usefulness of the SRFI a lot. i.e. there's still scope for implementors to break this convention, but if they don't need to then so much the better. For instance, the CPU-ARCHITECTURE can't really be interpreted without knowing the convention used by the OS. Knowing likely values for the OS-TYPE means you can at least base your cond-expand clauses on that. In strict standard terms, programs that relied on this would have indeterminate results according to the spec, but that wouldn't stop them being useful. For 100% reliable behaviour it would only be safe to cond-expand based on implementation/version combinations, which is a nightmare to use. Providing example output would also increase the usefulness of the SRFI as a reference for users, for instance I currently have no idea what a likely result of (c-memory-model) would look like (except that it can be #f). > In particular, if anyone knows how to emulate uname() on Windows, I > could add that information.
