  8. There's no `override' keyword because that would imply that derived classes
  9. may override _any_ visible method of the base class, e.g., as in Object
  10. Pascal.  In C++, the class designer decides which methods may be replaced
  11. in sub-classes, i.e., only those marked `virtual'.  It would be easier to
  12. get your compiler vendor to provide smarter error messages than to get the
  13. C++ committee to OK (what they would consider) an unnecessary new keyword.
