When comparing languages, posting unidiomatic code, and then making claims based on that unidiomatic code, is generally not fair nor correct.

That's true if the claims hinge on said unidiomatic code. As I said, it's not clear to me that that is the case here.

[questioner8216]

It seems completely clear. He first gives unidiomatic C++ code, then next gives idiomatic Rust code, and differentiates the two based on the code snippets. It is a mistake on his part, and I do not see how it could reasonably be viewed otherwise. It is not a huge mistake, but it is still a clear mistake.
