Strange variable scope... is this right?

When 'for f in f:' evaluates, the expression after 'in ' is evaluated,
and it results in the list. The for loop stores a reference to the list,
and sets f to the first element. In later iterations, the for loop still
remembers the list but otherwise it is gone.

After the loop, f points to the last thing it was set to (4, probably, from
the second loop). The list is gone.
