Thus, your example falls to case 1: "i" variable is newly declared for this loop. Well, we don't reuse old value of i to start the iteration from a particular place, like below?
i = 5 for i in [3,4,5,6,7]: print i,
More general, the variables could be assumed local only to the *same or higher* indentation level.
So (since you're talking about "if" as well as "for" and "while") you're suggesting that x = 0 if foo(): x = 1 else: x = 2 should always leave x == 0? Or that the same bit of code, without the first line, should always leave x undefined?

I always believed that the programming language (as any computer program) should slave to the human, rather than a human should slave to the program.
Right. And some of us humans *don't want* the change you're proposing. For what it's worth, I think it might well have been better if "for" and comprehensions had made their loop variables block-local; especially comprehensions. But making every for/while/if introduce a new level of scoping would be horrible. Perhaps you think it's what you want, but I think if you tried it for a month then you'd change your mind. -- g
