Comment:

 Though instantiated in `wp-settings.php`, within the class object itself,
 `WP_Locale` properties are being set in the `WP_Locale::init()` method
 (called from the constructor) ''before'' first being initialized as an
 array data type. I agree with the approach in
 [https://github.com/WordPress/wordpress-develop/pull/3824 PR 3824] as it
 reuses Core code designs and clearly communicates design intent at the
 property definition itself.

 I'd like to see a unit test added to the PR, which I will do today.
