<div dir="ltr">Agreed. I'm not convinced that this actually prevents any more errors than it might cause (forgot to finish writing my "repeat" block, and now my app is unresponsive), and I don't think there's enough of an expressivity win to add another keyword.<div><br></div><div>Austin</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 10, 2016 at 1:04 PM, Haravikk 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"><div style="word-wrap:break-word"><span class=""><br><div><blockquote type="cite"><div>On 10 May 2016, at 08:27, Nicholas Maccharoli via swift-evolution <<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>> wrote:</div><div><div dir="ltr"><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"><br></div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)">But I think it might be best to change the syntax / behaviour of `repeat` to loop </div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)">indefinitely if no trailing while clause is present:</div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"><br></div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"> repeat {</div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"> if ... { break }</div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"> //...</div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(39,78,19)"> }</div></div></div></blockquote><br></div></span><div>-1 from me on both counts; the thing I like about while true is that it’s explicit about what I meant, whereas a repeat block with no while clause is indistinguishable from me forgetting to include one, or me wanting an infinite loop.</div><div><br></div><div>An alternative could be to add a new “forever” keyword or something similar, replacing while true wherever applicable, but personally I don’t think it’s that important.</div></div><br>_______________________________________________<br>
