I don't quite follow your response. I want a program that initializes the 
generator from the global generator because I want different behavior every 
time I run it. So it will need IO. That's what I was trying to demonstrate. 
And I was wondering if one can get around the difficulty of passing the 
generator from call to call by using newStdGen in this way.
