            Move-construct a basic_writable_pipe from another.
          
basic_writable_pipe( basic_writable_pipe && other);
This constructor moves a pipe from one object to another.
                  The other basic_writable_pipe object
                  from which the move will occur.
                
            Following the move, the moved-from object is in the same state as if
            constructed using the basic_writable_pipe(const executor_type&)
            constructor.
