C++17 in Practice - The Good and the Ugly

Explore the good and ugly aspects of C++17 in this comprehensive conference talk. Delve into the complexities of the latest C++ standard, uncovering hidden features, design issues, and potential pitfalls. Learn about global objects, class template argument deduction, vectors, constructors, and compiler optimizations. Discover advanced topics such as attic templates, compile-time operations, undefined behavior, and fold expressions. Examine auto parameters in templates, optionals, and runtime polymorphism. Investigate string handling improvements, including string views, and explore the new file system capabilities. Gain insights into base initialization and other important C++17 features. Understand how to effectively utilize these enhancements in practice while avoiding common mistakes when combining new features.
