pyproject.toml requires mypy 1.4.0-1.5.0 + mypycify in setup.py: failure (AssertionError) #15877
Description
Bug Report
When upgrading a mypycify-using Python project from mypy 1.3.0 to a newer version, a pip install of my project fails where it does not with mypy 1.3.0
To Reproduce
git clone https://github.com/common-workflow-language/cwltool
cd cwltool
sed -i 's/mypy==1.3.0/mypy==1.4.0/' pyproject.toml # or to 1.4.1, or 1.5.0
MYPYPATH=mypy-stubs CWLTOOL_USE_MYPYC=1 pip install .Expected Behavior
$ MYPYPATH=mypy-stubs CWLTOOL_USE_MYPYC=1 pip install .

Actual Behavior
(passing --no-binary mypy to pip install to get a more interesting stacktrace, the same error occurs without it)

I've git bisected this error down to 768ba66 by @koogoro from #15070
(using its parent commit 3d9661c I don't get an error).
Therefore the
topic-mypyclabel should probably be removedmr-c commentedon Sep 15, 2023
