However, Doug balked at making this an implicit conversion, due to the ObjC-specificness and relative rarity of selectors. Implicit conversions tend to have hard-to-predict secondary costs.<br class=""><br class="">-Joe<br class=""><br class="">_______________________________________________<br class="">swift-evolution mailing list<br class=""><a href="mailto:swift-evolution@swift.org" class="">swift-evolution@swift.org</a><br class="">https://lists.swift.org/mailman/listinfo/swift-evolution<br class=""></div></div></blockquote></div><br class=""></div></div></body></html>
