Lambdas — even C++14's mysterious "generic lambdas" — are just syntactic sugar atop constructs that are perfectly understandable when approached from the right direction.

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.
