> Moving ownership between containers to avoid allocations was possible That's not the biggest upside of move semantics. You can't safely express smart pointers without move semantics. They tried with std::auto_ptr, and it didn't work.

Have a look at Qt implicit sharing. There is/was also a Boost library which could do most of it long before c++11.

  That's not the same as smart pointers like std::unique_ptr.

    Have a look at boost::movelib::unique_ptr<T> which works well with C++98/03.
