<div dir="ltr">The proposed `repeat { }` is identical to `while true { }`. One of these can happen accidentally because a trailing clause was unintentionally omitted, while the other cannot. One of these currently exists in the language, while the other does not. What is the motivation for having a new way of doing the same thing? I have not seen an answer.<div><br><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 10, 2016 at 4:05 PM, Taras Zakharko via swift-evolution <span dir="ltr"><<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">When I need a loop with complex control flow that does not fit into the classical while {} or repeat {} while structure, I use this:<br>
<br>
do_stuff: do {<br>
…<br>
continue do_stuff<br>
}<br>
<br>
This pattern explicit and allows very complex control flow patterns without the drawbacks of the unrestricted goto construct.<br>
<br>
Therefore I don’t see utility with having a repeat {} without while clause.<br>
