Things I wish I'd known from the start:

• Julia's C++ is "comically unidiomatic", as said by Stefan Karpinski. Specifically, you do NOT have to worry about anything resembling

1. template metaprogramming

2. fancy containers

3. move semantics

4. gnarly object oriented shenanigans like inheritance and the like

Greppin' around:

• To find a struct try: grep "} jl_binding_t;".

We basically just call the C++ API with a few range based for loops and lambdas sprinkled here and there. Let's show some examples.

• clang and clangd are NOT the same thing, nor are they bundled together. clangd is closer to clippy and it does not come preinstalled.

• libstdc++ and libc++ are the stdlibs pulled in by gcc and clang, respectively, make sure to update both of them before proceeding.

• If you want to compile a C++20 "Hello World like this one:

import <iostream>
int main() {
    std::cout << "hello world" << std::endl;
}

• I found the cpp reference and clangd extensions for VSCode to be crucial in navigating C++.

You should pass in the flags clang++ -std=c++20 test.cpp -o test.
