So what would your scheme do for the struct equivalent of this,
assuming it is even compiles:
```d
import std.stdio;
void main() {
Child child = new Child;
child.methB();
writeln();
Parent parent = child;
parent.methB;
}
class Parent {
void methB() {
writeln("MethB(P) ", typeof(this).stringof);
methC();
}
void methC() {
writeln("MethB(P) ", typeof(this).stringof);
}
}
class Child : Parent {
override void methC() {
writeln("MethC(C) ", typeof(this).stringof);
}
}
```
Where the above give this output:
```
$ ldc2 -run class.d
MethB(P) Parent
MethC(C) Child
MethB(P) Parent
MethC(C) Child
```
