Libraries that produce needless copies are simply ill-designed, The obvious case is return by value. I know that there are some compiler optimizations that can help here, but we have to work with the compilers we have.
The other case is standard containers (and yes, I know I snipped your comment that the standard library is badly designed). Until we have a C++09 compiler that supports move, maps etc involve a lot of copying.
- Sharing, if used, works way better with immutable objects. Well yes. I don't know about Hervé, but I would have thought a shared string class would indeed be immutable
