You are referring to intrusive members and this is the approach taken by 
intrusive_ptr<>.  Intrusive members become a problem when multiple 
inheritance is used and/or virtual inheritance because the intrusive 
member might or might not be duplicated in the object.

Perhaps an abbreviation can be used but for now this is the price to pay 
to use Shifted Pointer.
