Another benefit of this approach is that we can create different
behaviors without relying on the absurd subtleties of the preprocessor:

   typedef boost::shared_ptr<T> SharedT; // normal shared_ptr
   typedef boost::shared_ptr<assert_non_null<T>>
        NonNullSharedT; // no null enforced by assertions
   typedef boost::shared_ptr<enforce_non_null<T>>
         NeverNullSharedT; // no null enfoced by exceptions
