Dive into C++14 - [2] - `for_each_argument` explained and expanded

The second video covers a very interesting code snippet originally posted on Twitter by Sean Parent: `for_each_argument`. It shows and explains the usage of C 14 compile-time integer sequences, and analyzes a very interesting iterative implementation of an alternative version of Sean’s function that takes the desired arity as a template parameter. This tutorial video is a reviewed and improved version of my C Now 2015 lightning talk (“`for_each_arg` explained and expanded“).
