I forgot to mention, you have to include these two headers in shared_ptr.hpp.
#include <boost/type_traits.hpp> #include <boost/utility/enable_if.hpp>
Yes, and this is why the change isn't the no-brainer it seems at first. shared_ptr is a critical Boost component that has to work on every compiler supported by Boost (and a few unsupported ones.) So I tend to avoid problematic constructs and unnecessary dependencies. I agree that the feature is useful and will try to find a relatively painless way to incorporate it.
