[boost] Conversion from auto_ptr to scoped_ptr?

Hello there,

pardon me in advance if this is a FAQ but why is there no
costructor for scoped_ptr that takes a smart_ptr as an
argument?

Assuming, you have a funktion

std::auto_ptr<Obj> create_obj();

this would allow you to write

std::scoped_ptr<Obj> p(create_obj());

instead of

std::scoped_ptr<Obj> p(create_obj().release());

which is much better, IMO. And of course, it would mirror
shared_ptr, which has such a constructor.
