[panic] "too many cycle iterations" in robotframework #2637
Description
Summary
sorry it's not a minimal repro. i spent like an hour trying to minify this and gave up. i recommend adding robotframework to the primer if it's not there already because its types are so messed up and riddled with circular dependencies. possibly a similar issue to #601?
to reproduce
uv add robotframework- create a file with the following content:
from robot.running.model import Body Body.register
output
$ RUST_BACKTRACE=1 ty check pytest_robotframework/__init__.py
error[panic]: Panicked at /root/.cargo/git/checkouts/salsa-e6f3bb7c2a062968/0946cbd/src/function/execute.rs:633:9 when checking `/mnt/4tb-linux/projects/pytest-robotframework/pytest_robotframework/__init__.py`: `StaticClassLiteral < 'db >::inherited_legacy_generic_context_(Id(3c00)): execute: too many cycle iterations`
info: This indicates a bug in ty.
