+// This tests that attempting to perform ModuleDeclarationInstantation a
+// second time after a failure still fails. (It no longer stores and rethrows
+// the same error; the spec changed in that regard and the implementation was
+// updated in bug 1420420).
+//
+// The attempts fails becuase module 'a' is not available.
+//
+// This test exercises the path where the previously instantiated module is
+// re-instantiated directly.
