Perhaps examples from real world projects? Without being an expert I’m having a hard time seeing the full impact of the proposed rules. <div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Also, the @exclusivity syntax doesn’t seem fully defined. Is there a @exclusivity(checked) counterpart? Would subclasses be allowed to mark inherited properties more or less strictly? Also, is the logic for @ attributes and keyword attributes documented anywhere? Otherwise it seems like exclusive / nonexclusive would be an option.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Jon</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On May 2, 2017, at 4:07 PM, Ben Cohen via swift-evolution <<a href="mailto:swift-evolution@swift.org" class="">swift-evolution@swift.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=us-ascii" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class=""><p class="" style="-webkit-print-color-adjust: exact; margin-right: 0px; margin-bottom: 15px; margin-left: 0px; font-family: -apple-system-body, Helvetica, arial, sans-serif; background-color: rgb(255, 255, 255); margin-top: 0px !important;">Hello Swift community,</p><p class="" style="-webkit-print-color-adjust: exact; margin: 15px 0px; background-color: rgb(255, 255, 255);"><span style="font-family: -apple-system-body, Helvetica, arial, sans-serif;" class="">The review of SE-0176: "</span><font face="-apple-system-body, Helvetica, arial, sans-serif" class="">Enforce Exclusive Access to Memory"</font><span style="font-family: -apple-system-body, Helvetica, arial, sans-serif;" class=""> begins now and runs through May 8, 2017.</span></p><div class=""><p class="" style="-webkit-print-color-adjust: exact; margin: 15px 0px; font-family: -apple-system-body, Helvetica, arial, sans-serif; background-color: rgb(255, 255, 255);">The proposal is available here:</p><div class=""><a href="https://github.com/apple/swift-evolution/blob/master/proposals/0176-enforce-exclusive-access-to-memory.md" class="">https://github.com/apple/swift-evolution/blob/master/proposals/0176-enforce-exclusive-access-to-memory.md</a></div></div><div class=""><p class="" style="-webkit-print-color-adjust: exact; margin: 15px 0px; font-family: -apple-system-body, Helvetica, arial, sans-serif; background-color: rgb(255, 255, 255);">Reviews are an important part of the Swift evolution process.
