Charles,
Nothing I've seen so far envisages disturbing the existing, in my
opinion flawed, Matrix Class.
I trust that I have not missed anything.
Compilation is a complex press for a person unfamiliar with the C.
Anything you could do to simplify that would be welcome.

But NumPy already depends on BLAS and LAPACK, right?

It should also be possible to build reference cblas on top of blas_lite.
(Or just create a wrapper for the parts of cblas we need.)

Hi Matti,
I can definitely see how numpy changes cause trouble for you, and
sympathize. But, can you elaborate on wha

Hi. I am working on numpy in pypy. It would be much more challenging for
me if you merged more code into the core of numpy, that means even more
must be duplicated when using a different underlying ndarray
implementation.
If you are thinking of touching linalg/lapack_lite/blas_lite, I would
