Hm... I've noticed that you can't just call outer, you have to use  
this.outer.  Does anyone know if this is expected behavior or a bug?  Why  
would it be expected behavior?

This code compiles for me and works on dmd 2.033


import std.stdio;

public interface Listener {
     void handleEvent (int);
}

class Test{
     Listener listener;
     this(){
         listener    = new class() Listener {
             public void handleEvent(int evt) {
                 this.outer.toString(evt);
             }
         };
     }

     void call()
     {
         listener.handleEvent(0);
     }
     void toString(int evt){
         writefln("event is %d", evt);
     }
}

void main(){
     (new Test()).call();
}
