In the current SRFI 170 draft, as well as scsh, these are named: * user-(real-)uid * user-(real-)uid * user-effective-uid * user-effective-gid Should we use "get-" or "user-" for the prefix? I always thought the term "real user ID" is misleading: it sounds like the exact opposite of what it is. I would think the "real" ID is what's really used to check permissions. "Effective" is not misleading, and clarifies the meaning of "real", but that word is not used much anywhere else. These have the advantage that they are standard Unix terminology, but IMHO it would be nice if some more appropriate words can be found. The gist of it is identity vs permissions.
