## Summary - Emit diagnostics when looking up (possibly) unbound attributes - More explicit test assertions for unbound symbols - Review remaining call sites of `Symbol::ignore_possibly_unbound`. Most of them are something like `builtins_symbol(self.db, "Ellipsis").ignore_possibly_unbound().unwrap_or(Type::Unknown)` which look okay to me, unless we want to emit additional diagnostics. There is one additional case in enum literal handling, which has a TODO comment anyway. part of #14022 ## Test Plan New MD tests for (possibly) unbound attributes.
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.
