It’s not underscored so I’m assuming it’s an “official” part of the language. And "@inline(never) @inlinable" is a perfectly valid combination — it serializes the SIL for the function body, and while inlining it is prohibited, it is still subject to specialization, function signature optimizations, etc.</div><div class=""><br class=""></div><div class="">Slava</div></body></html>
