no side effects

[Michele Simionato]

I was surprised by the following code:

>>> for i in [1,2,3]:
...     print i,
...     i=3

I would have expected only 1 to be printed, but instead Python
continues the loop without noticing that the value of i has
changed. IOW, no side effect.
I am not against that (I am even in favor), but it fooled my 
intuition coming from other languages.
Maybe others will appreciate that.

Cheers,
