[pypy-dev] pickle numpy array from pypy to cpython?

[Eli Stevens (Gmail)]

No, since it's not *just* a numpy array I need to move around (dict
with numpy values, in this case, more complicated objects in the
future). Obviously I can kludge something manual together (assuming
the tofile/fromfile functions work cross-interpreter, which I wouldn't
take for granted at this point), but I'd rather be able to use pickle
(easier to work with libraries that also expect pickles, etc.).
