Two points:

  (a) `Class::new' should call `inherited' because it creates new
      anonymous subclass.  It's a bug.

  (b) In current implementation singleton class statement creates
      internal class, but it is just a virtual class, so that
      `inherited' is not called for them.  I consder it a feature.
