I have removed a bit where I say that rvalues are same as returned values, to avoid confusing other readers.
However, if the name was a very big string, i.e. something like file contents, and it would be necessary to ensure no copies for performance reasons, the unique_ptr or shared_ptr would come to the rescue
The purpose of the smart pointers unique_ptr and shared_ptr is to annotate ownership for heap allocated objects (unique vs shared ownership). They do help alleviate the thing you're describing, but shouldn't be used so liberally in that way since they heap allocate!
