Back to Basics: C++ Value Semantics - Klaus Iglberger - CppCon 2022
https://github.com/CppCon/CppCon2022


Modern C++ is more than new standards or an assortment of new features. Modern C++ is about a philosophy on how to use the language. An integral part of this philosophy is value semantics: preferring values and value-like types instead of pointers and references.

This talk explains the rational of this philosophy. It demonstrates the benefits of several value types from the standard library, such as std::optional, std::function and std::variant, and the drawbacks of several reference types, such as std::string_view and std::span. It also goes into detail about the most common questions about value semantics, as for instance how to properly use reference types and whether we should stop using reference parameters.
