BTW in your D foreach, you could also have done `switch`

   void trigger(string event) {
     switch(event) {
       foreach (i, e; events) {
         case e:
           foreach (c; callbacks_[i])
             c();
           return;
       }
       default:
            assert(false, "trying to trigger an unknown event: " ~ 
event);
     }
   }


And the compiler+runtime can optimize that into a binary search 
when it gets larger automatically.
