| In the documentation for the `traceback` module, the definitions of functions `extract_tb` [0], `format_list` [1] and classmethod `from_list` [2] mention the old style (4-)tuples that these functions used to return or accept. Since Python 3.5, however, they return or accept a FrameSummary object instead of the 4-tuple, or a StackSummary object instead of a list of 4-tuples. I'm including a patch that fixes these definitions to make them reflect the new reality.

| I think we need to decide whether this is a documentation bug or a regression in traceback module. See also issue 25573 for a similar report. |

| Hi Berker: It's a bit complicated—this specific issue I opened isn't a regression, because it's exactly the change that was intended: Use FrameSummary instead of a 4-tuple to pass the frame data. If you see the last comment for the issue 25573 you linked to, that issue has already been resolved by the docs being updated to reflect the new way of passing data. However, that is not to say there can't be regressions connected to this, but they have to do with the fact that FrameSummary implements only a subset of methods available of tuples. E.g. that FrameSummary does not implement __len__ like tuple does, see issue 26502. |

| This was a deliberate change in 3.5. Issue: https://bugs.python.org/issue17911 News entry: https://docs.python.org/3/whatsnew/3.5.html#traceback Why do you think it is a regression? Who would be the person that can decide if it is a doc bug or regression? |

| This is not a regression, the documentation was just not fully updated when the new feature was added. Patch looks good. This should probably be applied to the 3.5 branch as well. |
