Back to Basics: Lambdas from Scratch - Arthur O'Dwyer - CppCon 2019

We'll start with the implementation of C-style functions, then move to overloading, function templates, non-static member functions, C++11 lambdas, and then demystify C++14's generic lambdas. We'll cover the minor changes to lambdas in C++17, such as the ability to capture `*this` by value, and indicate some of the minor changes coming in C++2a. Finally, we'll detour into the implementations of std::function and std::bind to show how they're different from lambdas. Attendees will leave this session with a clear understanding of how C++ — a language without dynamic typing or garbage collection — can nevertheless support efficient lambda closures. — Arthur O'Dwyer New York Arthur O'Dwyer is the author of "Colossal Cave: The Board Game," "Mastering the C++17 STL" (the book), and "The STL From Scratch" (the training course).
