Pretty ugly :)

class B1 { int i; float f; };
class B2 { int j; float f; };

class D : B1, B2
{
    int i, j;
    float f;

    void fn()
    {
        ...
        int v = super::i; // refers to B1::i
        int w = super::j; // refers to B2::j
        float x = super::f; // error: ambiguous
        float y = super<B1>::f; // refers to B1::f
        float z = super<B2>::f; // refers to B2::f
        ...
    }
};

How ugly would the macros have to get to implement something like this with the 
current standards?
