[issue26502] traceback.extract_tb breaks compatibility by returning FrameSummary

[Berker Peksag]

Berker Peksag added the comment:

This is basically a duplicate of issue 25573. We need to add the examples in traceback module documentation to test_traceback.py.

IMO, the new FrameSummary API (and its friends) shouldn't change the return value of the existing traceback functions like extract_tb() so I'd say yes.
