>site.py adds the exit/quit Quitter instances to builtins (2.x

So it does. You learn something new every day...
When did that first happen? It was one of my biggest frustrations 
with Python when I first started learning, that you couldn't call exit
without first importing sys (v1.3). But I never noticed that changing 
till now.
