Nice that you started with C++23

[@theintjengineer]

Yaaay. New C++ stuff❤

I used VS code on windows 10, but it doesn't work. how can I run C++23 on VS code windows 10?

Hey Nick! Do you do 1-on-1 mentoring? I am a deep learning engineer by trade. I have a CS and applied math degree and want to switch to doing deeplearning compiler and performance engineering.

This will sound kind of weird, but I'm disappointed with the committee for adding yet another method for printing things, yet still not adding f-strings. Positional arguments are error prone and it's better for correctness to use std::cout even if it looks like garbage. However, if they had added f-strings, and admittedly that'd take a LOT of effort from compiler authors to implement, they could get a nice clean syntax that eliminates the positional argument problems. Probably not interesting, but I found when implementing them for my own language, that as I was doing so from scratch it was actually not particularly difficult to fit them in. Basically, I just have my compiler load const sections and run them at compile time and where types are not fully formed at compile time I split the string at those points and generate a call for the appropriate conversion function at run time. So in the worst case it works like std::cout, and in the best case it works like std::fputs() with a string literal. Of course, I fully admit that because I was doing things from scratch it was significantly easier to implement as I designed around this as one of my goals, but for preexisting compilers, especially those that use parser/lexer generators, it's not going to be as easy.

*"If (Score > 85) { std::print("pass"); } else { std::print("failed");}"* Ahh Test😮
