#8384: Make shared_ptr movable
------------------------------+---------------------------------------------
 Reporter:  viboes            |       Owner:  pdimov   
     Type:  Feature Requests  |      Status:  new      
Milestone:  To Be Determined  |   Component:  smart_ptr
  Version:  Boost 1.53.0      |    Severity:  Problem  
 Keywords:                    |  
------------------------------+---------------------------------------------
 std::shared_ptr is movable. I would be nice if boost::shared_ptr provides
 the same interface and use Boost.Move to make the code portable to non
 c++11 compilers.


 {{{
 shared_ptr(shared_ptr&& r) noexcept;
 template<class Y> shared_ptr(shared_ptr<Y>&& r) noexcept;
 20 Remark: The second constructor shall not participate in overload
 resolution unless Y* is convertible
 to T*.
 21 Effects: Move-constructs a shared_ptr instance from r.
 22 Postconditions: *this shall contain the old value of r. r shall be
 empty. r.get() == 0.
