[Boost-users] why doesn't scoped_ptr have a custom deleter?

 Hi,

I'm currently playing around with Apache's Xerces XML library, and found
myself needing to ->release some pointers. shared_ptr + mem_fn works great:

shared_ptr<DOMBuilder> db(
     impl->createBuilder()
   , mem_fn(&DOMBuilder::release)
);

But for the objects I'm using, I don't need a shared_ptr, but just a
scoped_ptr. So I'm wondering about the rationale behind not giving
scoped_ptr a custom deleter? Is it that shared_ptr's overhead is negligible
(when not being shared I mean)?

thanks
