Is there a way to make something like this work in D 2.0?
clone is supposed to make a new shallow copy of it's object:
interface Cloneable
{
const Cloneable clone();
}
class Demo : Cloneable
{
public :
this(){}
this( Demo reference )
{
reference_ = reference;
}
override const Demo clone() {
return new Demo( reference_ );
}
private:
Demo reference_;
}
void main()
{
auto a = new Demo(new Demo);
auto b = a.clone();
}
The method clone must be const and there must be a non-const constructor
in Demo.
