Lambdas from First Principles: A Whirlwind Tour of C++

by Arthur O'Dwyer

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Lambdas (even those 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 generic ("auto") lambdas. Finally, we'll detour into the implementations of std::function and std::bind to show how they're different from lambdas.
