After being confused I figured out it is a 3.x example:

----

$ python
Python 2.6.6 (r266:84292, Apr 20 2011, 11:58:30) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> fs=[]
>>> fs = [(lambda n: i + n) for i in range(10)]
>>> [fs[i](1) for i in range(10)]  
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

----

$ python3.1 
Python 3.1.3 (r313:86834, Nov 28 2010, 11:28:10) 
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> fs=[]
>>> fs = [(lambda n: i + n) for i in range(10)]
>>> [fs[i](1) for i in range(10)]  
[10, 10, 10, 10, 10, 10, 10, 10, 10, 10]

Is this fixed automatically by 2to3?
