I plan to give a brand-new talk for the first time at C&B, but I’m conflicted regarding what to say about it here because it’s recently been a bit of a startling realization to me about C++11, and I think it may be a bit startling for others too. I don’t want to be a tease, but I also want to save it as a surprise for C&B itself.
In the meantime, here’s a teaser…
In addition to the many new C++11 features that everyone’s listing, it has dawned on me over the winter that there’s actually another major change that isn’t being talked about anywhere, or even being listed as a change in C++11 at all as far as I know, because I and other key experts and committee members I’ve asked didn’t fully realize that we altered the basic meaning of not one but two fundamental keywords in C++. It’s a change that has profound consequences, that rewrites and/or invalidates several pieces of pre-C++11 design guidance, and that’s directly related to writing solid code in a concurrent and parallel world. This isn’t just an academic change, either — everyone is going to have to learn and apply the new C++11 guidance that we’ll cover in this session.
I plan to talk about it first at C&B, in a session tentatively titled as above — I’ll fill in the keywords later. You may already guess a few keyword candidates based on the description above, and here’s a final hint: You’ll hardly find two C++ keywords that are older, or whose meanings are more changed from C++98 to C++11. (No, they aren’t auto and register.)
