Summary
This episode explores how C++20's lambda enhancements significantly improve resource management patterns. Jason demonstrates a practical application of default constructible stateless lambdas and lambdas in unevaluated contexts by showing how to create a custom deleter for std::unique_ptr. By comparing C++17 and C++20 approaches, he illustrates how the new features eliminate boilerplate code when managing FILE* resources, resulting in cleaner and more maintainable code without any performance penalties.
