I am assuming I am at the right tribune! (Let me know otherwise) I would suggest to add a constructor (as well as the supporting members and rules) to scoped_ptr<> that could allow specifying a deleter, as per: template scoped_ptr(Y * p, D d); as the same exists for shared_ptr<>. The deleter feature in shared_ptr is very useful for raii with any kind of resource (variables, functions, objects, etc.). Having it in scoped_ptr will offer the same advantage for noncopyable pointers. Thank you.
