The shared_ptr implementation would have to check its template argument and emit special code in a few places. This is very easy to do, and far easier than specializing/wrapping the class.

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 NonNullSharedT; // no null enforced by assertions typedef boost::shared_ptr NeverNullSharedT; // no null enfoced by exceptions regards -Thorsten
