Back to Basics - Name Lookup and Overload Resolution in C++ - Mateusz Pusz - CppCon 2022
github.com/Cpp...
This talk explains how name lookup and overload resolution works. The language rules are not easy at all and may not be what one could expect. During the lecture, I will describe in detail how the process works, what are the pitfalls, and how to avoid them.
This talk is part of the Back to Basics track and the material will be targeted to include all skill levels. Familiarity with the C++ language is recommended however no prior knowledge of name lookup or function overloads is required.

Sorry, I got lost a bit on the question asked in the 47th minute. I realized the answer right after finishing the lecture. As I mentoned, I should provide a default implementation in the CPO rather then calling std::swap there. I did this last minute change for the needs of slideware without thinking about it too much. The reason for not using std::swap directly there is because we do not want to include all overloads of this function from namespace std into the lookup (i e. the one for std::string).
Great talk Mateusz. Thanks.
Mateusz, great talk! Thank you! EPAM is a great place to work!
