you can do it that way if you wanted to

    let mut i = 0;
    for item in items {
      item.method(i);
      i += 1;
    }

I don't know why you'd it that way, but Rust definitely isn't stopping you from doing that.

e: and as running example: https://play.rust-lang.org/?version=stable&mode=debug&editio...

Well, the complaint in the article is that the idiomatic way is kind of inscrutable. I'm more than willing to let pragmatism win in those cases, since so many languages make this pattern a nuisance instead of providing a simple "enumerate this array with index" out-of-the-box as part of the standard library. IIRC you have to roll your own in Java, C#, and Powershell.

In C# there's a .Select overload, that gives your lambda both item and its index.
