Summary
Jason explores ways to create a more modern, type-safe version of the main() function in C++. He demonstrates a pattern that forward-declares a better_main() function inside main() that takes a span of string_view arguments instead of the traditional (int argc, char* argv[]) parameters. Jason compares two implementations: one using a vector for dynamic allocation and another using a fixed-size array with stack allocation. He discusses the trade-offs and benefits of this approach, including improved type safety, const-correctness, easier command-line argument handling, and the ability to enforce constraints like noexcept on the main function's implementation.
