I still find myself hoping (probably futilely) that Bjarne Stroustrop will come out with a new edition of The C++ Programming Language, to help me understand all the features that have been added to it since C++14...
Thank you! I knew that existed, but now that I read the synopsis I'm thinking that the C++20/23 material makes sense in this "tour" book... the C++11 (and earlier) material in The C++ Programming Language is like the basis for the language, and everything that came after is more advanced in usage. I guess.
Anyway, maybe all obvious observations but thank you nonetheless
