It is a good point, and a slight oversight in the current design that
it is not possible.  

We probably want some type of general index-mapping object, which
could perhaps also handle sparse matrices.  I will have to think about
it for a while.

Thanks, I've added the extra information.  The performance extensions
originally caught my eye... some nice ideas there.
