I have been using enums to define error numbers within a specific class.
I now want to derive a class from this base. I would also like to derive
the enum from the base.
 
For example

class A
{
  enum AError
  {
    eErrorOpen, eErrorClose
  }
};
 
class B : public A
{
  enum BError : AError
  {
    eErrorPipeOpen     // Would start at one more than AError::eErrorClose
  }
};

Has anyone ever wanted to do this or is there another way of doing
the same thing.
Is this a possibility of being added to the C++ standard.
