You can implement an opIndex overload that returns a struct that 
itself supports opDispatch.

```d
struct Foo
{
     struct opIndexResult
     {
         Foo* that;
         auto opDispatch(string member, T)(T t)
         {

         }
     }

     auto opIndex(T)(T t)
     {
         return opIndexResult(&this);
     }
}

void main()
{
     Foo foo;
     foo[1337].isnull = true;
}
```

dont underestimate what's already possible !
