Also see https://bugs.python.org/issue1660500 for the original Python 3.0 change to hide the iteration variable. While the test suite already covers some interesting scoping edge cases as result of that initial patch, I think one we're currently missing is the nested comprehension case: >>> [[x for x in range(1, i)] for i in range(2, 5)] [[1], [1, 2], [1, 2, 3]]
