Jeffrey Yasskin <jyass...@gmail.com> added the comment: I've updated for_iter.patch to the latest trunk, merging in issue 4715. I also changed tracing a bit so that the first line of a loop doesn't get traced twice in the first iteration, and added to test_dis to check that decreasing line numbers work there.
