C++Now 2021

In this talk, you are going to learn about one of the flagship features of C++20, concepts. We are going to discover together the main motivations behind concepts, why templates as-is are not enough and how concepts came to the rescue. Then we are going into details into the 4 different ways we can use a concept and the pros and cons for each way. Obviously, this session would be delusional without learning how to write our own concepts, so we're going to spend around half of the session writing new concepts.
