How would we evaluate the proposal to introduce the "sealed" specifier for classes (open within module, final outside of module) and default to that, in terms of source-code compatibility? <br>From my point of view it might be easier to do before Swift 3, but if delayed until Swift 4 it wouldn't be the most time-consuming breakage for developers. <br><div class="gmail_quote"><div dir="ltr">On Wed, Jun 22, 2016 at 9:09 AM Matthew Johnson 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 style="word-wrap:break-word"><div><blockquote type="cite"><div>On Jun 22, 2016, at 10:59 AM, John McCall <<a href="mailto:rjmccall@apple.com" target="_blank">rjmccall@apple.com</a>> wrote:</div><br><div><div style="word-wrap:break-word"><br><div><blockquote type="cite"><div>On Jun 22, 2016, at 8:17 AM, Matthew Johnson via swift-evolution <<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>> wrote:</div><br><div><div style="word-wrap:break-word"><div><blockquote type="cite"><div style="word-wrap:break-word"><div><ul><li>Rationalizing base conversion protocol names.
