[issue38535] Incorrect col_offset for decorators with zero arguments (empty parentheses)

[issue13672] Add co_qualname attribute in code objects

Alex Hall added the comment: I think this would be very useful in tracebacks. If a traceback line had a more useful name like `MyClass.__init__` instead of just `__init__` or `my_decorator..wrapper` instead of just `wrapper` it would provide useful context to the frame. -- nosy
