There was a problem hiding this comment.
I suspect that self.breaking_out = False should be left here. I can try to come up with a test case, but if nothing breaks, I'd leave it.

OK, added it back. I was wondering about that; it's unclear even after scanning all the code exactly how this flag is used. |

The exact semantics aren't entirely clean to me either. They way I understand it is that it will be true when statements following the current statement can't be reached -- for example, after a return statement. It gets trickier when there is non-trivial control flow such as within a try statement. |
