I see, think it can be done with mixin:
```d
template prn(alias args)
{
   string prn()
   {
     string result = "write(";
     foreach(s; args.split("|"))
     {
       result ~= format("%s,", s);
     }
     return result ~ ");";
   }
}

void main()
{
   int data = 456;
   char enter = '\n';

   mixin(prn!q{
     enter| 123 | " str " |  data |

     enter|    __TIME__   | enter }
   );

   mixin(
     prn!q{"This value of " |41| " is prime."}
   );
}
```

If there was some convenience on the compiler side, we could 
integrate it into D.
