After reading it again I take it you want auto_ptr to inherit a class.
But in you want how it destroys the object you will STILL have to have an
extra class.  So you really did not save anything.

Also for other "smart" pointers the delete is not always in the
destructor..... It is best to pass in a function object (or something
similar) to control how the object is destroyed.
