I think it's a bug, because the following works:
```d
import std.stdio;
struct abc{
int[100] a;
int opIndex(int index){
return a[index];
}
int opIndexUnary(string s)(int index)
if(s == "++"){
return ++a[index];
}
int[] opUnary(string s)() if (s == "++"){
return a[] += 1;
}
}
void main (){
abc s;
int[100] a;
int temp;
writeln (a[20]++);
writeln(a[20]);
writeln(++s[20]);
writeln(s[20]);
//writeln(s[0]++);// doesn't work for some reason
writeln(s[0]);
writeln(s++);//but this works!!
writeln(s);
}
```
```D
writeln(++s[0]); // should work
writeln(s++); // this calls opUnary if I'm not mistaken
```
