Ok. In that case, it is fair to say that you are talking about a full
reimplementation of the whole scipy ecosystem, at least as much as
pypy itself is a reimplementation of python  ? (since none of the
existing ecosystem will work without the C numpy API). Sorry for being
dense, just want to make sure I am not misrepresenting your approach,
