Proposed resolution:

Strike [futures.promise] p6 and change p7: 

promise& operator=(promise&& rhs);

-6- Effects: move assigns its associated state to rhs.

-7- Postcondition: *this has no associated state. associated state of *this is the same as the associated state of rhs before the call. rhs has no associated state.

Addresses UK 339 [CD1]

Move assignment is going in the wrong direction, assigning from *this to the passed rvalue, and then returning a reference to an unusable *this.
