eigenvalues are not part of Numeric, they are in the LinearAlgebra
modules (where they should be) The LnuearAlgebra module is generally
distributed with Numeric, but that is part of the batteries included
philosphy. Surely you wouldn't want people ot have to install yet
another package to get Linear Algebra functionality?

That is a very good argument for including NumPy in the standard
library, not for duplicating its functionality in the library.

Hopefully, it will happen.

BTW, MacPython includes Numeric, and it is part of the extended module
support of ActiveState Python, so it's really not hard for your users to
download.
