`an_array.into_iter()` currently just works because of the autoref feature, which then calls `<[T] as IntoIterator>::into_iter`. But in the future, arrays will implement `IntoIterator`, too. In order to avoid problems in the future, the call is replaced by `iter()` which is shorter and more explicit.
