In Python:

    sum(range(10))

In Rust:

    Vec![1..10].iter().reduce(|x,y| x+y)

View on HN

In Rust: (1..10).sum()

I guess that shows how new I still am at Rust...

All these languages took a lot from Lisp (especially former) and functional languages (especially latter). So it's like complaining to Newton that's his laws of mechanics are known by almost everyone these days, so Newton did nothing special.

I'm not complaining. I just wanted to add more languages.

In Raku:

    sum(1..10)
    (1..10).sum

or just

    sum 1..10

Or more generically: [+] 1..10

You can use any infix op (core or custom) to do a reduction:

[*] 1..10 # 3628800 basically faculty
