## Summary This adds a new diagnostic when possibly unbound symbols are imported. The `TODO` comment had a question mark, do I'm not sure if this is really something that we want. This does not touch the un*declared* case, yet. relates to: #14022 ## Test Plan Updated already existing tests with new diagnostics
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.
