This provides for static upcast. But what about static downcast? Maybe
something like:
shared_ptr<Base> base(new Base);
shared_ptr<Derived> derived(do_static_cast<Derived>(base));
A do_dynamic_cast is also needed. I'd hate for the programmer to not have
the choice of whether to use a static or dynamic cast.
