Why doesn't scoped_ptr have an additional template parameter to accept a deleter?

Because that would make it larger than sizeof (T*). I believe the general consensus on this is to use shared_ptr or perhaps the upcoming policy_ptr.

The size could be kept as is in the case that no deleter is specified, or even if a stateless deleter were specified. I'd like to see a deleter parameter to scoped_ptr. Another option is to use static_move_ptr (which I will probably renamed unique_ptr soon): http://www.kangaroologic.com/move_ptr/ Jonathan
