Yeah, after some time pondering on it, I was going for a similar
solution; I was thinking of doing it the traditional OO way, using a
constructor method to return a Dice_Pool object with the Generator intialized,
and a Roll method to generate a result. 

Hadn't thought of the exact way to implement this, but it would not have
looked a lot different from your example.

Thanks,

Mart
