Comment (by holmes@…):

 a description of the term move semantics can be found here
 http://www.cprogramming.com/c++11/rvalue-references-and-move-semantics-

 in-c++11.html

 Here is an example of what I would like to do which works with a
 std::deque :


 {{{
 std::deque<std::unique_ptr<int>> myQueue;
 std::unique_ptr<int> myP(new int(4));
 myQueue.push_back(std::move(myP));              //transfer ownership to
 the queue
 auto otherP = std::move(myQueue.front());       //transfer ownership back
 from the queue to a new unique_ptr
 myQueue.pop_front();
 }}}

 This doesn't work with boost::circular_buffer because there is only one
 overload of push_back and it takes a const T&. I need another overload
 that takes T&&.
