A well designed opDollar is still an enhancement request:  
http://d.puremagic.com/issues/show_bug.cgi?id=3474. However, there is a  
hack to get $ to return a value. Unfortunately, I've lost that newsgroup  
post.

Memory got me this code snippet:


struct Bar {
     int opIndex(int i) { writeln(i); return i; }

}
int __dollar() { return 5;}


void main(string[] args) {
     Bar b;
     b[$];
}
