How to do "inheritance" in D structs

[lobo via Digitalmars-d-learn]

Hi,

I'm coming from C++ and wondered if the pattern below has an 
equivalent in D using structs. I could just use classes and leave 
it up to the caller to use scoped! as well but I'm not sure how 
that will play out when others start using my lib.

Thanks,
lobo


module A;

class Base1 {
     int ival = 42;
}
class Base2 {
     int ival = 84;
}

module B;

class S(ABase) : ABase {
     string sval = "hello";
}

module C;

import A;
import B;

void main() {
     auto s= scoped!(S!Base1); // scoped!(S!Base2)
}
