Hi Howard,<br><br>The removal of BitwiseOperations is not under review here; that, like signum(), has been considered twice and approved twice, and has not been revised.<br><br><div class="gmail_quote"><div dir="ltr">On Thu, Jul 20, 2017 at 19:36 Howard Lovatt 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 dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space"><div>The revised version of the proposal can be found here:</div><div><a href="https://github.com/apple/swift-evolution/blob/master/proposals/0104-improved-integers.md" target="_blank">https://github.com/apple/swift-evolution/blob/master/proposals/0104-improved-integers.md</a></div><div><br></div><div><span class="m_2994816141908992432m_1574666041005850135Apple-tab-span" style="white-space:pre-wrap"> </span>• What is your evaluation of the proposal?<br></div></div></blockquote></div></div></div><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space"></div></blockquote><div><br></div><div>Overall +1. Two reservations:</div><div><br></div><div> 1. Functions like `signum()` that return a property would read better as a property!</div><div> 2. I have found `BitwiseOperations` useful as an extension to both Bool and Set and for a custom set type.
