New submission from Antoine Pitrou:
This can be considered a regression, although perhaps it may not be desirable
to fix it in a later release.
In 3.4:
>>> def f(): return traceback.extract_stack()
...
>>> print([x[0:3] for x in f()])
[('<stdin>', 1, '<module>'), ('<stdin>', 1, 'f')]
In 3.5:
>>> print([x[0:3] for x in f()])
[('<stdin>', 1, '<module>'), ('<stdin>', 1, 'f'),
('/home/antoine/35/lib/python3.5/traceback.py', 201, 'extract_stack')]
Note how the traceback module suddenly appears in the extracted stack. This
breaks any application which uses a fixed offset into the returned stack to
look up for information.
