Gday, I'm using VS 2012 and cpython 3.3.
I've noted that there is no code outlining (the collapsible boxes) for if statements as well as it treating for loops strangely. When you add in a for loop it looks up in the document for something to attach it to.
Screenshot details a small case displaying the problem. Adding and removing the import causes the following result.
Without import, inlining moves by 1 row
