## Summary This PR adds a suite of tests for wildcard (`*`) imports. The tests nearly all fail for now, and those that don't, ahem, pass for the wrong reasons... I've tried to add TODO comments in all instances for places where we are currently inferring the incorrect thing, incorrectly emitting a diagnostic, or emitting a diagnostic with a bad error message. ## Test Plan `cargo test -p red_knot_python_semantic`
Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/red_knot_test/README.md for documentation of this test format.
