This is the wrapper I ended up with. I had to remove the throw, it
triggered all the time.

template<typename Moveable>
struct PretendToBeCopyable
{
        explicit PretendToBeCopyable(Moveable&& m) : m(std::move(m)) {}
        PretendToBeCopyable(PretendToBeCopyable&&) = default;
        PretendToBeCopyable(PretendToBeCopyable& p)
                : m(std::move(p.m)) {}
        void operator()() { m(); }
private:
        Moveable m;
};

}
