This is really fantastic. Thanks a lot Sturla for keeping us in the loop. Also, I am sure that you had an important technical role in this.
If I am right, this will be in the scipy 0.16 release, which means that when we move to depending on 0.16 we should rewrite our computational linear algebra code.
