    /**
     * @see  https://www.php.net/manual/en/function.array-merge-recursive.php#92195
    * array_merge_recursive does indeed merge arrays, but it converts values with duplicate
    * keys to arrays rather than overwriting the value in the first array with the duplicate
    * value in the second array, as array_merge does. I.e., with array_merge_recursive,
    * this happens (documented behavior):
    *
    * array_merge_recursive(array('key' => 'org value'), array('key' => 'new value'));
    *     => array('key' => array('org value', 'new value'));
    *
    * array_merge_recursive_distinct does not change the datatypes of the values in the arrays.
    * Matching keys' values in the second array overwrite those in the first array, as is the
    * case with array_merge, i.e.:
    *
    * array_merge_recursive_distinct(array('key' => 'org value'), array('key' => 'new value'));
    *     => array('key' => array('new value'));
    *
    * Parameters are passed by reference, though only for performance reasons. They're not
    * altered by this function.
