/* Here's a fragment of a Scala encoding for the Keris module system;
** the compiler claims:
**
** 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...
