How long is it from the time a new language is released until we can start calling some of its users old school ;-) I'm a little surprised that you have found the performance implications unconvincing in discussions where the OGs advocate devectorization. The main performance win from devectorization is that you avoid allocating temporary containers to hold the results of intermediate computations. When this matters, it is often a pretty big deal. Here's a link to one vectorized vs devectorized performance comparison that I worked on a while ago: https://news.ycombinator.com/item?id=7450601 I don't think there's anything too special about that one, except that I have a link to it. Other examples abound on the mailing list.
