This is a bit weird and hard to read. Do you mean the following?
```csharp
foreach (var t in world.WorldActor.TraitsImplementing<INotifyChat>())
{
   if (t.OnChat(player, order.TargetString)
   {
      Game.AddChatLine(client.Color.RGB, client.Name + suffix, order.TargetString);
      continue;
   }
}
