Description

This is sort of the opposite of #456. I recently wrote let idx = v.iter().enumerate().find(|&(_, &ch)| ch == '|').unwrap().0, when I should have written let idx = v.iter().position(|&ch| ch == '|').unwrap(). I'd have to think a little on the exact rule that should be followed here, but it would be nice if clippy could catch this pattern.
