Re: [Boost-Users] Any interest in a weak pointer?

Is there any interest in a weak pointer that plays well with shared_ptr and its friends?

Both Greg Colvin and Peter Dimov (and others?) have worked on the idea off and on. I think they are "on" at the moment. On the main Boost list we are also looking hard at the Loki::SmartPtr. It would be interesting to try to implement cyclic_ptr, weak_ptr, and the like as a SmartPtr OwnershipPolicy. The thinking is that the future of smart pointers isn't to keep adding completely separate classes. But rather to add more instances of policy classes to a Loki::SmartPtr style framework.
