Try:

    auto gen2 = new MtClass19937(unpredictableSeed);
    /* the above is just MersenneTwister tweaked to be
     * a final class, hence reference type
     */
    auto r5 = simpleRandomRange(0.0L, 1.0L, gen2);
    auto arr1 = array(r5.save.take(5));
    auto arr2 = array(r5.take(5));
    writeln(arr1);
    writeln(arr2);

... and you get two different sequences of numbers.
