Exercise 3.66: Examine the stream (pairs
integers integers). Can you make any general comments about the order in which
the pairs are placed into the stream? For example, approximately how many pairs precede
the pair (1, 100)?  the pair (99, 100)? the pair (100, 100)? (If you can make
precise mathematical statements here, all the better. But feel free to give
more qualitative answers if you find yourself getting bogged down.)
