I know there is no current plan to implement scipy in pypy, but searching the PyPy website, I was not able to find the reason. If it is not to be included as a feature due to lack of interest or developer time, I am offering to begin rewriting scipy in pure python (I have quite a bit of free time to do this). If it has been discussed and actively excluded from pypy, I would like to know that before I waste too much time rewriting it. I have an active interest in being able to use some modules which depend on scipy while using the PyPy interpreter (especially pyBrain). I have seen the hack on the pypy blog: http://morepypy.blogspot.com/2011/12/plotting-using-matplotlib-from-pypy.htm... I could simply use the hack myself, but unless there's a reason not too, I think it'd be nice to have scipy available as a pure python module (perhaps called scipypy in the same manner as numpy). -- Steven Jackson
