Great, now I am confused again - just while thinking about it. :)
Why not simply define swap as
template <typename OtherDerived>
void swap(MatrixBase<OtherDerived> m);
I mean in any case. It does not really matter whether a matrix is
passed or not - what we will copy is always only MatrixBase and that's
tiny, right?
