D - bug in template subclasses

Hi,
The following code doesn't compile.
template A(T) {
public interface I {
public T i();
}
}
class B : instance A(int).I {
public int i() {
return 42;
}
}
int main() {
B b = new B();
instance A(int).I i = b;
printf("B.i -> %d\r\n", b.i());
printf("I.i -> %d\r\n", i.i());
return 0;
}
The inheritance declaration of B doesn't accept a anonymous template
instance, but accepts a qualified one.
Best regards,
Daniel Yokomiso.
