?year ago, everyone was all but certain that the C++0x standard was just around the corner, and that it would include concepts (see Danny Kalev’s earlier interview with Bjarne Stroustrup, the creator of C++, from August 2008). However, In July 2009 the C++ standards committee decided to remove concepts from the C++0x by an unprecedented move. Danny’s recent controversial editorial was among the first to report that decision and its possible consequences. Despite vociferous disagreements over the removal of concepts themselves, nearly everyone agrees that the committee’s decision left open many questions not only about concepts, but also about the committee’s charter, and even the future of C++ itself.

Therefore, Danny has interviewed Bjarne Stroustrup again, this time to capture his thoughts about concepts, their removal, and the impact of that decision, along with his take on other pressing questions that currently concern the entire C++ community.
