Herb Sutter has in the past year made a convincing case that “the free lunch is over” for performance and that languages cannot ignore concurrency and remain relevant. His PDC talk introduces his thoughts for “Concur:” a set of conforming extensions to C++ that provides high-level abstractions (“active” objects and “future” results). In my opinion, the best talk of the PDC and it’s available online.

 He also briefly mentions C++/LINQ, which is the first I’ve heard about a commitment towards providing that capability in C++.

 (I’m confused how it can be “conforming” though, since at the very least it seems to require active as a keyword, but…)
