Isn't that the same as "doesn't provide a body"?
import std.stdio;
class A {
abstract void fun() { writeln("wyda"); }
}
class B : A {
void fun() { A.fun(); }
}
unittest {
A a = new B;
a.fun();
a.A.fun();
}
Not a rhetorical or a loaded question: Has that sort of thing ever been
useful?
I was wondering the same. It's also very bug prone because when
overriding the function you must remember to invoke the super method, a
thing you can forget.
