Personally, I am not sure that generalizing take is the right approach. Take is currently orthogonal to indexing implementation wise and has some smaller differences. Given a good idea for the api, I think a new function maybe better. Since I am not on a computer at the moment I did not check the old discussions though. - Sebastian _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > http://mail.scipy.org/mailman/listinfo/numpy-discussion _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
