Yeah. I've seen this called hiding, shadowing and overwriting 
earlier, but never overriding - that's always been reserved for 
the polymorphic kind.

I'd argue the documentation should use one of those other terms.

Steve showed a few posts up one example that would make it 
basically impossible. Other language features make it even worse:

     class A { private void fun() {} }
     class B(string s) : A { mixin(s); }
