using System;

 namespace A {

 interface IA {
     void Test();
 }

 class Base<T> where T : class, IA {
     public void ImplTest() {
         (this as T).Test();
     }
 }

 class A : Base<A>, IA {
     public void Test() {
         Console.WriteLine(“A.Test()”);
     }
 }

 public class _ {
     public static void Main(string[] args) {
         new A().ImplTest();
     }
 }
 }

for(Item item : items) {}

or like this at my spare time:

foreach(Item item in items {}

That’s funny, it’s not actually annoying, it’s pure fun, I like my job and I like what I’m doing in my spare time :).
