It's not a compelling feature, but if added, it needs to be part of the declaration, not the implementation, where the caller can see it. Realistically, though, it doesn't have much optimization value. Functions that don't return tend not to be called many times. (You could potentially have a function that never returned normally, but could throw an exception. This might be useful when starting up some task which normally runs forever but could fail, throw, and be restarted by its caller.) John Nagle Animats --- [ comp.std.c++ is moderated.
