It’s true that the variant of the issue involving explicit references seems pretty unique to Go. But there are plenty of languages that have the variant of the issue where a closure implicitly captures a local variable by reference. JavaScript used to have it until `let` was created (and still does have it if you don’t use `let`). And I ran into it recently in some closure-heavy Python code I wrote recently. (Python makes it relatively ugly to work around, too.)
