[boost] Re: const_pointer_cast for shared_ptr

I would like to propose adding const_pointer_cast<> to shared_ptr, in exactly the same way that there is dynamic_pointer_cast<> and static_pointer_cast<>.

I am surprised that it is missing. Is there a reason for that?

If not, I will submit a patch that implements this.

Thanks.

Isn't it already there? I see it on line 378 of shared_ptr.hpp in boost 1.31. Bob
