CppCon 2023

Join me on an introductory journey into polymorphism that doesn't use class inheritance and virtual functions. I'll share my amazement at how polymorphism permeates C++. Then we'll visit the long-used Curiously Recurring Template Pattern (CRTP) with its modernization using implicit this.

Do you like lambdas? So does the override pattern, which uses them to handle std::tuples and std::variants with std::apply and std::visit.

Want to walk through a container of disparate types invoking their functions? You'll see this and all the above in code examples galore.

Afterward, you'll be eager to learn more on your own!
