Parent destructors are called automatically:

import std.stdio;
class Foo {
	~this() { writeln("Foo.dtor"); }
}
class Bar : Foo {
	~this() { writeln("Bar.dtor"); }
}

void main() {
	auto f = new Bar();
}

$ ./test500
Bar.dtor
Foo.dtor


But if you want to do it explicitly, you can with "super.__dtor();

class Bar : Foo {
         ~this() {
                 writeln("Bar.dtor");
                 super.__dtor();
         }
}


Notice that it is still called automatically, so it goes twice:


Bar.dtor
Foo.dtor
Foo.dtor
