Bug#1024861: contextlib2: (autopkgtest) needs update for python3.11: 'mycontext' object does not support the context manager protocol

Source: contextlib2
Version: 0.6.0.post1-2
Severity: serious

Control: affects -1 src:python3-defaults

Dear maintainer(s),

We are in the transition of adding python3.11 as a supported Python
version [0]. With a recent upload of python3-defaults the autopkgtest of
contextlib2 fails in testing when that autopkgtest is run with the
binary packages of python3-defaults from unstable. It passes when run
with only packages from testing. In tabular form:

pass fail
python3-defaults from testing 3.10.6-3
contextlib2 from testing 0.6.0.post1-2
all others from testing from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of python3-defaults
to testing [1]. https://docs.python.org/3/whatsnew/3.11.html lists
what's new in Python3.11, it may help to identify what needs to be updated.
