I'm using Python 3.10, the 24.10.31 release of flake8-bugbear and these inputs:

python-attrs@24.2.0 python-flake8@4.0.1 python-hypothesis@6.121.0 python-hypothesmith@0.1.9
+ python-pytest@8.3.3 python-setuptools@67.6.1 python-wheel@0.40.0

Thank you!

Perhaps hypothesis is too new?

Ah, hypothesmith>=0.2 -- my environment doesn't meet it; it's at 0.1.9 due to >= 0.2 requiring rust-based libcst, which I haven't figured out how to build in an isolated environment (cargo wants to pull dependencies from the net).
