405-411: Optimize redundant string cloning.

The logic for calculating qualname is correct, but there's an opportunity to optimize the string handling.

Apply this diff to avoid redundant cloning:

-        // Calculate qualname based on the current qualified path
-        let qualname = if self.qualified_path.is_empty() {
-            Some(obj_name.clone())
-        } else {
-            Some(self.qualified_path.join("."))
-        };
+        // Calculate qualname based on the current qualified path
+        let qualname = if self.qualified_path.is_empty() {
+            Some(obj_name.clone())
+        } else {
+            Some(self.qualified_path.join("."))
+        };

Actually, the current implementation is fine. The obj_name is used later in the struct, so the clone is necessary.

313-314: Consider refactoring to reduce code duplication.

The pattern of updating qualname after pushing qualified paths is repeated across functions, classes, and comprehensions. While the current implementation is correct, consider extracting this into a helper method to improve maintainability.

Consider adding a helper method like:

fn update_qualname_from_path(&mut self) {
    let qualified_name = self.qualified_path.join(".");
    self.code_stack.last_mut().unwrap().qualname = Some(qualified_name);
}

This would reduce the repeated pattern of self.qualified_path.join(".") and make the intent clearer.

vm/src/builtins/code.rs (2)

301-304: LGTM! Clean implementation of co_qualname getter.

The implementation follows the same pattern as other code object getters and correctly exposes the qualified name to Python code.

---

408-408: Good preservation of qualname in replace method.

The qualified name is correctly preserved when creating replaced code objects, ensuring consistency with the original code object's identity.

compiler/codegen/src/ir.rs (2)

76-76: Well-designed optional qualname field.

The optional qualname field allows flexible qualified name tracking during code generation, with appropriate fallback handling in finalize_code.

---

167-168: Correct fallback logic for qualname.

The implementation properly falls back to obj_name when qualname is not set, ensuring code objects always have a qualified name. The clone() is necessary since obj_name is moved in the destructuring.

compiler/core/src/bytecode.rs (3)

118-119: Clean addition of qualname field with proper documentation.

The field is correctly typed as C::Name and includes helpful documentation referencing CPython's co_qualname for clarity.

---

1145-1145: Consistent qualname mapping in map_bag method.

The qualified name is properly mapped using bag.make_name(), maintaining consistency with other name field mappings like obj_name and source_path.

---

1175-1175: Consistent qualname mapping in map_clone_bag method.

The qualified name mapping in the clone variant follows the same pattern as the non-clone version, ensuring consistency across both mapping methods.

compiler/core/src/marshal.rs (3)

213-214: Correct deserialization of qualname field.

The qualified name is properly read from the marshaled data using the same pattern as other string fields, with appropriate length-prefixed reading.

---

256-256: Proper inclusion of qualname in CodeObject construction.

The deserialized qualified name is correctly included in the CodeObject construction, maintaining field order consistency.

---

616-616: Symmetric serialization of qualname field.

The qualified name is properly serialized using write_vec() in the same position as it's read during deserialization, ensuring symmetric marshaling behavior.

compiler/codegen/src/compile.rs (6)

313-314: LGTM: Proper initialization of qualname in constructor.

The qualname is correctly initialized to the code name in the Compiler::new constructor, establishing the base case for module-level code objects.

---

420-420: LGTM: Qualname correctly stored in CodeInfo.

The qualname field is properly included in the ir::CodeInfo structure creation.

---

507-509: LGTM: Function qualname correctly updated.

The qualname is appropriately updated after establishing the qualified path for the function, ensuring it reflects the full qualified name.

---

513-514: LGTM: Lambda qualname follows Python conventions.

Setting the lambda qualname to "<lambda>" is correct and follows standard Python behavior for anonymous functions.

---

735-736: LGTM: Class qualname handling is consistent.

The qualname update for classes follows the same pattern as functions, ensuring consistency across different code object types.

---

978-979: LGTM: Comprehension qualname correctly set.

Setting the comprehension qualname to the comprehension name (e.g., "<listcomp>") is appropriate and follows Python conventions.
