Cunning non-zero pointer for objects that can be cloned.
The pointer is guaranteed to always point to something. Used to record base class pointers to objects When copied, the object pointed to gets cloned. When written or read to/from binary streams, suitable polymorphic I/O is invoked.
To take ownership of the contents of a vcl_auto_ptr<T> use
vcl_auto_ptr<T> inst = get_from_some_factory_function(); mbl_cloneable_nzptr<T> long_term_store(inst.release());
