Hi Nicolas,

Very nice! It’s great to have a fast library for linear algebra.

Unfortunately, the state of diff tools in Pharo6, be it thru MC or worse than all, thru legacy change lists, does not enable such a large scale review, so I think that I will edit in Squeak and run in Pharo...
> Now that Smallapack supports Opal, there should be no major problem for porting to Pharo7, but I did not have time to try yet. A few more MC regressions, and the fact to forbid protocol beginning with a * was too serious a cross compatibility hurdle for me. But I'll come back to it, tools are generally better in ph7 than ph6. Stay tuned.
