ROTFL. You made my day. Martin asks increasingly narrowly.focused questions, and you make that into me being defensive. Yeah, right. Obviously, I beg to differ. It's not *my* view. It's just not *your* view: - Scott Meyers: https://www.youtube.com/watch?v=WDIkqP4JbkE - Chandler Carruth: https://www.youtube.com/watch?v=fHNmRkzxHWs - Herb Sutter: https://www.youtube.com/watch?v=L7zSU9HI-6I - Alex Stepanov & Bjarne Stroustup: http://www.stepanovpapers.com/container_benchmark.cpp - Ulrich Drepper: http://www.akkadia.org/drepper/cpumemory.pdf Clearly, all of the above (and Thiago, and Peppe, and Milian) are all wrong and I am part of a big conspiracy. > Clearly Marc should write a /book/ about which tricks should be applied > when writing high performance code. Those books have already been written. You should read them! - Herb Sutter: Exception C++, More Exceptional C++, C++ Coding Standards - Scott Meyers: Effective C++, More Effective C++, Effective STL, Effective Modern C++ - ... I expect you to view those videos and to read those articles and then I expect you to apologise for this mail of yours.
