Is there a way to call methods in a parent class? Even if the child class overloads the method definition?

Take a look at this code:

class baseClass {
	public void doSomething(int x) {
		return x+1;
	}
}


class derivedClass: baseClass {
	public void doSomething(int x) {
		x *=2;
		return baseClass.doSomething(x);
	}
}

I haven't seen anything in the D spec that hints at this kind of functionality. Is this currently possible, and I'm just not aware of it? If it's not possible, is there any good reason why we couldn't add this to the spec?

yes super.method( .... ); as in ...
------------------
import c.stdio;

class A {
 this() { printf("A::this()\n"); }
 void show() { printf("A::show()\n"); }
}

class B : A {
 this() { printf("B::this()\n"); }
 void show() { super.show(); printf("B::show()\n"); }
}

int main( char[][] args ) {
 B b = new B();
 b.show();
 return 0;
}


// output (as you would expect)
//A::this()
//B::this()
//A::show()
//B::show()

Aha. Fantastic. This really ought to be documented on the "functions.html" page or the "classes.html" page (which mentions using "super" to call parent-class constructors, but not other methods) on the digital mars website.
