+/* Original comment:
+ * Here's a fragment of a Scala encoding for the Keris module system;

+**
+** S5.scala:28: value n in class N of type N.this._N.n
+** cannot override value n in class M of type M.this._N.n
+**        val system = new M() with N() {}
+**                         ^
+** To me it seems like the code is perfectly fine...
