I don't have experience of too many other languages, but in C++ (and I
guess C)...

for (int i=0; i<10; ++i)
{
    doStuff(i);
}

doStuff(i); // Error

int i;

for (i=0; i<10;++i)
{
    doStuff(i);
}

doStuff(i); // No error

That's the behaviour I was expecting.

Is the Python behaviour just a happy side effect of the target list
assignment or specific design decision?
