Exactly. Being able to treat the values of a header as both an array and a string are the best of both worlds:

```php
echo $response->getHeader('Cache-Control');
//> no-cache, no-store

echo $response->getHeader('Cache-Control')[0];
//> no-cache

echo count($response->getHeader('Cache-Control'));
//> 2

foreach ($response->getHeader('Cache-Control') as $index => $value) {
    echo $value . ', ';
}
//> no-cache, no-store
```
