Give C++ "inline" its original and obvious meaning

Excellent article.

This is a complete waste of time. inlining is an optimization. Optimizations are always subject to improvement. Therefore, inlining is subject to improvement.

Removing the optimizer from inlining isn't where we are going, it just isn't going to happen, ever, get over it.

What isn't a waste of time, would be to point out a case where the optimizer gets it wrong, and explain what would be better, and then we can retune the optimizer to be _better_ without that being at the expense of other code. We already knew that some of the heuristics are probably wrong for C. If people want, we can bump up the numbers a ton for the heuristic for things marked with inline (or whatever else anyone would like) and then wait for the bug reports that said we went too far, and then bump them back down some...

It would be good if we could sign up lots of people to benchmark their favorite programs as we tune it around, and give timely feedback on them so that we know how things are being impacted.
