I'm interested in using a pattern like:</div><div class=""><br class=""></div><div class=""><font face="Menlo" class="">func doAnimations() {</font></div><div class=""><font face="Menlo" class=""> AnimationContext(speed: 1.0, bounciness: 1.0)</font></div><div class=""><font face="Menlo" class=""> // do some animations using these options</font></div><div class=""><font face="Menlo" class="">}</font></div><div class=""><br class=""></div><div class="">But today, the value returned by <font face="Menlo" class="">AnimationContext(speed:bounciness:)</font> gets deinitted immediately.</div><div class=""><br class=""></div><div class="">I've come to desire using such a pattern after living with this for a while:</div><div class=""><br class=""></div><div class=""><font face="Menlo" class="">AnimationContext(speed: 1.0, bounciness: 1.0) {</font></div><div class=""><font face="Menlo" class=""> // do some animations using these options<span class="Apple-tab-span" style="white-space: pre;"> </span></font></div><div class=""><font face="Menlo" class="">}</font></div><div class=""><br class=""></div><div class="">But I don't like it because it contributes heavily to rightward drift (a user of this API might want to change the options multiple times), and gets hard to parse when nested in the many other language constructs that create a scope using brackets.</div><div class=""><br class=""></div><div class="">So — would it be reasonable to suggest that we have some keyword(s) preceeding an initializer that allows a value to stay alive and/or not warn if it winds up going unused? The current behavior in Swift has obviously been considered, so please feel free to tell me if this is a Very Bad Idea. I'm still learning!</div><div class=""><br class=""></div><div class="">- Ollie</div></body></html>
