Maybe that's a dumb question (which would be embarassing, because I typically think of myself as a good C++ programmer), but why use a reference in the return type anyway instead of the "real thing"? If a copy is created anyway, the "&" doesn't have any advantage, or am I missing something? "const string&" would only make sense if a string was returned which is typically stored in the object and should _not_ be copied, e.g. in a getter-method. Am I missing something?
