Very useful links. Clearly, `cycle` is a related topic. It's at once more general, in that it would operate on sequences and produce an infinite sequence, and much more tricky to implement, as evidenced by the extensive discussion on support for cycling infinite sequences. Both of those factors could arguably change the balance in terms of thresholds for inclusion in the standard library.<br><div class="gmail_quote"><div dir="ltr">On Tue, May 2, 2017 at 11:40 Ole Begemann via swift-evolution <<a href="mailto:swift-evolution@swift.org">swift-evolution@swift.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000">
