How would you argue that abstract is basically a no-op when used on
methods with bodies?
It's not a no-op. Try it.
Yeah, not *currently*, but isn't that what you're proposing?
No. I think it would help going back to my original message instead of
asking one-liner questions. This would work much better in real life,
but it's a time sink in a newsgroup. You spend five seconds on asking
a question with a foregone answer just because you don't want to
invest fifteen seconds in re-reading my initial post, and then you
have me spend five minutes explain things again. It's counter-productive.
If a class defines an abstract method and also provides a body for it,
it still requires the derived class to override the method. So
abstract still has some meaning.
Umm... so it defines a body that will never be used because that class
can't be instantiated and the method must be redefined by subclasses?
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();
}
