+# Runtime behavior involving non-data descriptors in dataclasses is

+# implementations.
+#
+# In particular:
+# - DC2.x and DC2.y raise AttributeError at runtime because no descriptor
+#   instance is stored in the class dictionary for those fields.
+# - dc2.x and dc2.y evaluate to the stored Desc2 instances because
+#   non-data descriptors are shadowed by instance attributes.
+# - The behavior for z is also subtle because dataclasses access the
