Three C++23 features for common use

C++23 is the current working version of the C++ standard. No major feature has been included so far, but a series of smaller ones as well as many defect reports have made it already to the standard. Many of these new features are small improvements or things you probably wouldn’t use on a regular basis. However, I want to point here to three C++23 features that, in my opinion, stand out among the others as more likely to be used more often.
