Your best bet is to set that `$args` property in a new method and call it from the constructor. Here's a rough outline:

```php
protected $args = array();
public function __construct() { $this->set_default_args(); }
protected function set_default_args() {
    $this->args = array( ... );
}
```

That would be the ideal way, but you could also reassign those keys from the constructor, too:

`$this->args['label_next'] = __( 'Next', 'posts-in-page' );`
