And it's been magical to see that an idea written here, pitched convincingly, comes into being in the next version of a programming language.</div><div><br></div><div>Except it's not magic. Dozens if not hundreds of people spend time thinking about and debating concrete implementation details, then a group of people painstakingly implements the result. During the Swift 3 time frame, the illusion of magic fell apart because even some excellently pitched ideas, carefully thought out, never became reality. This results in a huge loss of time and effort. Everything that didn't make it into Swift 3 needs to be re-evaluated to some extent because features are not designed in a vacuum and must fit in with the rest of the language. The best solution for a problem that we could design after the Swift 2 release would look very different from the best solution that we can design now.</div><div><br></div><div>The point is, since nothing is really magic, we have to make a concession to the reality that ideas too far from identified priorities are much less likely to become part of the next release. It may be fun and creative to think about how, hypothetically, one would design dynamic facilities to support Swift 3, but the truth is that there will never be a release based on Swift 3 that additionally has dynamic facilities. It is simply not a productive use of anyone's creativity, time, or effort to imagine how that might look; we're better off channeling everyone's energy towards making the real, actual upcoming release of Swift even better.</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="word-wrap:break-word"><div><div><div class="gmail-h5"><div><div><blockquote type="cite"><div>On 12 Oct 2016, at 21:48, David Hart <<a href="mailto:david@hartbit.com" target="_blank">david@hartbit.com</a>> wrote:</div><br class="gmail-m_-685145878912053630Apple-interchange-newline"><div><div style="word-wrap:break-word"><div>Hello Ted,</div><div><br></div><div>Please try to understand.
