And another consequence of this change is that the following code breaks
with decltype-based result_of for a non-nullary function object F

    template <typename F>
    struct FuncWrapper
    {
        typename boost::result_of<F()>::type operator()();

        /* ... */
    };

as described in [Part 2 of 3] of my reply to Daniel.
