I've dealt with this issue in Git.  Unfortunately there is a test suite
error remaining:


set -e; for v in 3.9; do \
        PATH=$PATH:/build/mypy-0.790/debian/mypy/usr/bin/ python$v -m pytest -n auto \
        -o testpaths=mypy/test -o python_files=test*.py \
        -k "not StubtestMiscUnit" \
        -o python_classes= -o python_functions=; \
done
