Sure does. And as you said, that's the easy step. It's a small,
localized patch; I'll send it along shortly.

My first target will be diag * sparse and sparse * diag. I had
tried to jump in whole-hog, but somehow DEFBINOP_OP spun off into
an infinite recursion. But that was the sketch last night, and
now I'm heading in the more sensible way.

Oh, I would like to see many things, particularly templates
rather than macros and a sprinkling of OpenMP. But that will
have to be evolutionary as well. I'll post what I have once
something sensible works.
