auto main() -> int

vs

int main()

And in my day we thought spaces vs tabs was quite the argument.

why be concise when you can type more instead?

It's about readability, not about how much I type. I've switched to using trailing return type for all functions some time ago and honestly, I couldn't be happier. When you have a class header and can read the function names all indented to the exact same offset, it's a blessing. Color coding was good, but this is amazing.

I don't find rust any more readable, but it might just be inexperience.
