Let me rephrase that without the "english" part.

"for line in file" maps exactly the language-independent representation of 
the process which I form in my mind, which makes such expression simple, 
consistent, easy to learn and all that.

"for i in 10" doesn't map any of my representations of an enumeration up to 
10, much less one from 0 to 9.

You don't have to tell me that. I'm Italian :)
