     This is embarassing, but I'm actually not sure where I talked about an
interface specifically.  I did rather nebulously talk about interfacing with
C code and LAPACK and the interfaces there would be provided by the
respective code and consumed by micronumpy, at least as I currently see it.
     I haven't consulted maciej about this yet, but I think working
backwards from a complete C NumPy depends on a great deal of "ifs", many of
which I think aren't satisfied.  I need to look into this, but I assume
NumPy operates on array structures directly, rather than through an
interface. If it's through an interface, there's a real possibility that
approach is possible, though it would require me to write some adaptors, I
think it would be ok, and a low enough time investment. Like I said I'm
currently speaking from ignorance so I need to look into it and get back to
you.

Cheers,
Dan

P.S. I agree about the sparse matrices, I've bugged fijal a small bit about
that.

P.P.S. Forgot to CC the mailing list... assumed this mail client would do it
for me.. lol
