I am still living in the 2.x world because all the things I want to do

This should be enough to convince you:
~ : python
Python 2.7.1 (r271:86832, May 3 2011, 10:31:28)
1< "1"
True
~ : python3
Python 3.2 (r32:88445, May 3 2011, 13:26:55)
1< "1"
Traceback (most recent call last):
File "<stdin>", line 1, in<module>
TypeError: unorderable types: int()< str()
Maybe with Python 4, '1< True' will give a TypeError too ;-).
Or if that's not enough,
~ : python
Python 2.7.1 (r271:86832, May 3 2011, 10:31:28)
True, False = False, True
"True is " + ("True" if True else "False")
'True is False'
~ : python3
Python 3.2 (r32:88445, May 3 2011, 13:26:55)
True, False = False, True
File "<stdin>", line 1
SyntaxError: assignment to keyword
Somehow I could hear Sean saying something like: "Yeah... and so?"
