Actually, I'm not sure how you implement the standard requirement in C++03.
If you do that:
The signature of these constructors depends upon whether D is a
If D is non-reference type A, then the signatures are:
unique_ptr(pointer p, const A& d);
unique_ptr(pointer p, A&& d);
(and it seems that you do) deleter rvalues will always bind to A const& in
C++03, never to rv<A>, as we saw in the recent thread. So it seems that
unique_ptr<T>( p, D() )
will fail for a movable, noncopyable, D.
unique_ptr<T>( p, move(d) )
will work though.
