I find it really problematic that the "classic first program" in this book includes "import std;" as the very first line, and as far as I know not a single compiler with the possible exception of MSVC supports that out of the box.
Writing this on a debian machine, and trying "g++ --std=c++23 -fmodules-ts" does not work, and from https://en.cppreference.com/w/cpp/23 looks like the "paper" for this is P2465R3, for which clang++ 17 has "partial support". I apt installed clang++17, and it still didn't work, complaining "module 'std' not found"
I understand that "import std;" is a very new feature and not "finalized" or whatever, but this book is supposed to be for beginners to C++; I wonder how the average beginner would react to that?
(I found the same thing a year or two ago when reading "Tour of C++")
