A related warning can be see with this C# program:


using System;
namespace Test {
    class Foo {
        int x;
        private void Add(int y) {
            x += y;
        }
        static void Main() {
            System.Console.WriteLine("test");
        }
    }
}



Compiled with mono:
...gmcs test.cs
test.cs(5,22): warning CS0169: The private method `Test.Foo.Add(int)' is never
used
Compilation succeeded - 1 warning(s)


In D private methods can be used by other functions in the same module, so it's
less easy to produce a warning like this.
