But the Ref<> class does not support std::swap correctly

Yes, and we don't intent to support that (the same way you can't swap plain references). The reason why supporting this wouldn't be a good idea is that it's not evident whether the content or the references are swapped.

At the moment, there is no easy work-around for you -- eventually, we plan to support Eigen::Ptr. You can try overloading swap(Ref, Ref), implemented using placement-new -- but you'd sail at your own risk then ...
