It sounds interesting, but could you offer a sketch of what this
might look like?  Do you mean one in which one or more policies
are fixed, and the pointer is parameterized on the remaining policies?
Like so:

smart_ptr<T, p1, p2, p3, p4>

smart_ptr_p1<T, p2, p3, p4>

smart_ptr_p1_p2<T, p3, p4>

Or do you mean something completely different?
