ah sorry, I think I misunderstood your email.
You would like pypy+numpy+scipy so that you could write fast python-only
algorithms and still use the existing libraries. I suppose this is a
perfectly reasonable usecase, and indeed the current plan does not focus on this.
However, I'd like to underline that to write "fast python-only algorithms",
you most probably still need a fast numpy in the way it is written right now
(unless you want to write your algorithms without using numpy at all). If we
went to the slow-but-scipy-compatible approach, any pure python algorithm
which interfaces with numpy arrays would be terribly slow.
