Agreed that mixing the two is a bad idea. So I suppose that you are suggesting to use `npy_intp`. But then, I'd say that `size_t` being unsigned, is a better fit for describing a memory length. Mmh, I'll stick with `size_t` for the time being (unless anyone else can convince me that this is really a big mistake ;-) -- Francesc Alted _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
