Hi, Boost has a lot of pieces of the c++11 header <memory>, shared_ptr, weak_ptr , ... in Boost.SmartPtr, unique_ptr, allocator argument tag, uses_allocator ... in Boost.Interprocess. Other are already in the C++03 <memory> header. Others are missing, as pointer_traits, default_delete, ... I would like we complete all these features and move them to a Boost.Memory library smoothly (something like the Boost.Utility). As these are standard features, I propose to use directly the boost namespace for them. boost memory.hpp memory pointer_traits_hpp ... unique_ptr.hpp shared_ptr.hpp weak_ptr.hpp ... What do you think? Best, Vicente
