# The next 3 lines compute 2**32582656 in less than a
minute on my system:


a = 2 ** (2**10 * 9)
b = 1
3541.times { b*=a }
# a**3541, which equals 2**32582656, will fail to
# execute in ruby, but the 3541.times works


# this next line, however,

s = b.to_s

# takes a _very_ long time
# similar (but much longer, I think) to Python's
# rendering of b into a string.
