this is true, however, it could be a way to ensure through the use of only standard C++ techniques that you don't have an unnecessary copy operation. if you make sure that the object you're...
I guess I optimistically hoped that the semantics of returning an r-value reference would allow the object to survive somehow beyond the end of the scope, just long enough to have its data copied. ...
in standard C++, returning a temporary is really about the only way of doing it cleanly.
if you are using a compiler that supports the new standard (C++2011), you can return an rvalue reference as...
