People who remember when I posted the factorial of 65,536 surely remember that my Ruby script took ~4:30 minutes to complete while a Python2.1 script took over 12 minutes. *I downloaded Python2.2 (which now unifies short integer and long integers) and tried the script again. *Here are the new results:
