Chapter 25. `inline` Redux

Difficulty: 7

Quick: When is inlining performed? And is it possible to write a function that can be guar-anteed never to be inlined? In this Item, we'll consider the many and varied opportunities for inlining, including many that are likely to surprise you. The answers, stated simply, are, “It's never too late, and nothing is impossible…”
