One I didn't see here which has been a pleasure to use lately: https://en.cppreference.com/w/cpp/container/map/extract

Used to update map keys without reallocation.

Thank you! I do this kind of operation a lot and had no idea this new method existed in C++17.

One thing that I miss in C++ is a bit more clarity on how copy elision and NRVO kick in. To me it feels a bit hand-wavy.

This article makes a good point in showcasing clear examples.
