    /**
     * Determines the relative position of the object on the left with respect to the one on the right.
     *
     * This method is compatible with core types and other types. You can implement `NelsonMartell\IComparable`
     * in order to improve the beaviour for other classes.
     *
     * This method can be used as sorting function for `usort()` function.
     *
     * **Notes:**
     * - Comparison is made in natural way if they are of the same type. If not, is used the PHP standard
     * comparison.
     * - If ``$left`` and ``$right`` are arrays, comparison is made by first by 'key' (as strings) and then by
     *   'values' (using this method recursively).
     *
     * **Override:**
     * You can override this method to implement a contextual sorting behaviour for `usort()` function.
     * If you only need to compare instances of your class with other objects, implement `NelsonMartell\IComparable`
     * instead.
     *
     * @param mixed $left  Left object.
     * @param mixed $right Right object.

     *   - ``> 0`` if $left is considered greater than $other;
     *   - ``< 0`` if $left is considered less than $other;
     *   - ``null`` if $left can't be compared to $other .
