Thank you I tried it, at the https://tour.dlang.org/ rdmd 
Playground and
got a casting error, so I changed ```string``` to ```char[8]``` 
and it worked:
no return needed: (?)
```
import std.stdio;
void main()
{
  enum Dlang99 = 4026728633831507;

   union Magic
   {
     long data;
     char[8] bits;
     char[8] toString()
     {
       return bits;
     }
   }
   auto magic = Magic(Dlang99<<10|'D');
        magic.writefln!"..::%s::..";
}

```
