Same for Rust.

I tend to use for loops in Rust for this reason; simple, and understandable by anyone who's programmed in an imperative language.

The one-liner approach tends to include an explicit type declaration (Or turbofish), `iter()`, and `collect()`, at minimum.

FYI I think you've misinterpreted the parent. To my eyes it looks like they're agreeing that Rust makes summing a list easy using combinations. For example, this is how I would do it in Rust:

  x.iter().sum()

I think they’ve understood and are claiming that a simple loop is cleaner than what you wrote. I’m not sure how since that 1 line communicates what’s happening at a high level with 1 word “sum” whereas a loop requires me to read the loop to confirm it’s a plain summation.

This sounds like someone complaining that the concepts they learned when they were first starting out are the only concepts that programming languages should introduce which is silly - technology evolves as we find better and new ways of accomplishing old tasks.
