The author states:

>Neither the performance issue that move semantics address nor the perfect forwarding problem exist in classic OO languages that use reference semantics and garbage collection for user-defined types."

I understand reference semantics but what are move semantics?

Also what is the "perfect forwarding problem"?

Author here. A few years back, I wrote an article about the issues that you're asking about. Since the article still comes up as the #1 result of Google search for "C++ rvalue references", I believe it's ok for me to recommend it here:

Warning: Read only if you have a serious interest in C++.
