C++ has multiple inheritance, while java and C# do not, so super would be ambigous.
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?
You'd have to use SFINAE to tell whether B1::j exists and use B2::j otherwise. Should be doable.
