Je suis désolé :-( So you are *not* using Python 2.3.
I have verified your observation (non-existent __iter__()) for Python 2.2.1
and have no idea how the for loop works there. 

However, the code I posted *will* work for 2.2.1 if you put

from __future__ import generators

at the start of the file, i. e. before all other statements including
 
import something.else

Hope that helps,
