  When dealing with random number generators, it's a very common principle,
that trying to make a good RNG better by adding more clutter to it usually
makes it a lot worse. (The natural way of thinking that "a more complicated
function will probably lead to a more complicated result" is usually quite
false when dealing with RNGs. Usually when trying to make the function
"more complicated" you end up with an extremely poor RNG.)
