+Builtin Type Alias False Positive Test
+=======================================
+
+This tests that builtin types like ``list`` in function signatures do not
+incorrectly link to class attributes with the same name.
+
+
+.. py:module:: mymodule
+
+   Module to test builtin type cross-reference false positives.
+
+
+.. py:class:: MyClass
+
+   A class with an attribute that shadows a builtin type name.
+
+   .. py:attribute:: list
+      :value: [1, 2, 3]
+
+      An attribute named ``list`` that shadows the builtin.
+
+
+.. py:function:: process(items: list) -> None
+   :module: mymodule
+
+   Process a list of items.
+
+   The ``list`` type annotation here should NOT link to ``MyClass.list``.
