In this blog post, we’ll explore ways to improve the safety of a simple configuration manager. We’ll handle common pitfalls like dangling references and excessive stack usage. Additionally, we’ll see how C++26 helps enforce safer coding practices with stricter diagnostics and improved handling of large objects. Let’s go. Step 1: The Buggy Implementation Below is a simple example of a manager object that stores various configs in a map and provides a method to retrieve them.
