I think we can provide functions for the most common smart pointers to 
be registered directly:

hold_with_auto_ptr(A)   # or perhaps: auto_ptr_holder(A)?
hold_with_smart_ptr(A)

And a more general purpose function for any other smart pointer:

hold(A, 'my_smart_ptr<A>')

It does duplicate information, but very little in my opinion.
