Is it possible to get the count of a class defined static array? For example:

class Model_Example
{

    const VALUE_2 = 2;
    const VALUE_3 = 3;

    public static $value_array = array(
        self::VALUE_1 => 'boing',
        self::VALUE_2 => 'boingboing',
        self::VALUE_3 => 'boingboingboing',
    );

    public function countit()
    {
        // count number
        $total = count(self::$value_array );
        echo ': ';
        die($total);
    }
}
