CodeCompletion: inherit bug?

[gonboy]

//father
class A
{
   public:
      char a;
};
//son
class B
{
   public:
      char b;
}

int main()
{
   B x;
   x.b = 12;
   x.A::a = 45; //Couldn't Complete it ".A::a"

   return 0
}

It should be "class B : public A", but I suppose this advanced syntax is not supported anyway.
