Sorry for the long delay.</div><div><br class=""></div><div>The consensus of the internal language-review team is that we think this is a great idea, but that it should be more generally opt-in rather than being tied to hard-coded types. There are two dimensions of this.</div><div><br class=""></div><div>The first is that you should add an attribute, __attribute__((objc_boxable)), that goes on struct declarations. The @(…) syntax should only allow a struct operand if it has this attribute. Make sure you test the __has_attribute for this. You should also make sure that redeclarations after the definition can add this attribute and have it still be respected by the type-checker; this will be extremely useful for people migrating code to SDKs that lack these attributes.</div><div><br class=""></div><div>The second is that the implicit code pattern shouldn’t try to use the convenience factory methods; just use +[NSValue valueWithBytes:objCType:].</div><div><br class=""></div><div>John.</div></body></html>
