Okay, maybe "useless" is a bit much, but the cases where _ would be most useful and those where you're likely to want to use iterators: you want to avoid processing a whole pile of data again. Also, the interface more or less has to make a choice between using iterators and lists, I think (at least for the "map python over this input data" case) - so either the default wouldn't work for large datasets, or _ wouldn't be useful.<br><div><br></div><div>Ed Kellett</div><br><div class="gmail_quote">On Sat Jan 17 2015 at 00:39:25 Ethan Furman <<a href="mailto:ethan@stoneleaf.us">ethan@stoneleaf.us</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 01/16/2015 02:00 PM, Ed Kellett wrote:<br>

Just because '_' isn't useful in the iterator case doesn't mean it's also useless for other situations.<br>
