The following code does not compile.

import std.stdio;
interface A {
    public void a(int l);
}
class ACl:A {
    public void a(int l) {
        writeln("Hello a");
    }
}

interface B: public A {
    public void a(string l, int k);
}

class BCl: ACl, B {
    public void a(string l, int k) {
        writeln("Hello B.a", l, k);
    }
}


int main() {
    B b = new BCl();
    b.a(1);
    return 0;
}

However changing the second line of main() to (cast(A)b).a(1) makes it work.
