You mean it's not backward compatible because it won't generate exactly the same sequence of output for a given seed, and therefore we wouldn't want to make that change? I think it's somewhat debatable whether generating a different sequence of random numbers counts as breaking backward compatibility. -- -- Those who don't understand recursion are doomed to repeat it _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
