Off the top of my head you do something like https://play.rust-lang.org/?version=stable&mode=debug&editio...

Yeah you gotta write it out per number of times. Luckily this rarely comes up in this specific form.

Wow, that code is as bad as I thought it would be. Yeesh.

> Luckily this rarely comes up in this specific form.

Well, yeah—it would come up rarely because it only solves the problem under very specific circumstances!

Yeah I mean you might be able to make it better, this is just what I would reach for first.

It is so rare that I don’t think I’ve ever seen it in any rust codebase I’ve ever looked at.
