C++ Metaprogramming: Ditching IILEs in Favor of Expansion Statements and Structured Bindings
2025-03-26
This blog post explores how to streamline C++ metaprogramming, reducing reliance on Immediately Invoked Lambda Expressions (IILEs) by leveraging the `expand` helper, expansion statements, and structured bindings. It details element-wise expansion, early returns, and returning values, showing how to transform arbitrary ranges into packs for efficient compile-time data manipulation. These techniques significantly improve code readability and maintainability, avoiding verbose coding practices.
