That's almost exactly what Peter's new shared_ptr has. But it doesn't use a
function<void>, instead it takes any object, d, that can be invoked as


where x is the T* managed by shared_ptr.

I can imagine people wanting this in scoped_ptr too, but Peter didn't take
that on yet, in part because adding any additional overhead for scoped_ptr
is far more controversial than adding a bit of overhead to shared_ptr.
