Nth Pack Element in C++ - A Case Study

Explore various techniques for accessing the nth element of a variadic pack in C++ through this comprehensive conference talk from CppCon 2022. Delve into approaches ranging from naive implementations to advanced template meta-programming tricks and compiler intrinsics. Gain insights into C++20 features that enable new methods for handling variadic packs. Compare different solutions, including compilation times and readability, across languages like Rust, Nim, D, Circle, and C++. Enhance your understanding of modern C++ development, focusing on performance and quality, while learning from Senior Software Architect Kris Jusiak's expertise in template meta-programming and domain-specific languages.
