+# ABOUT:
+#
+#  This test tests for unusual use of Native Types,
+#  specificially, creation of 3rd Party Native types using the Core Native Types infrastructure,
+#  but without having the definitions of all the accessors under the primary Moose namespace,
+#  so that the only element needed under the Moose namespace is the registration node.
