Huh?  Adding pointwise addition means you have to add eigenvalues?

The reason I don't want to use NumPy is that it isn't included in
standard Python distributions.  It's yet another thing for the user
to download, and it's maintained and distributed by a separate group
of people than the Python maintainers.  All in all, it's harder to
deal with and there's more ways to go wrong.

If NumPy became part of standard Python, then I'd happily use it.

Will do.
