This is a really good alternative.  Because I used to have to 
write longer.  Thanks, the LOG thing is better now:


```d
struct LOG(T...) {
  T[0] id;
  T[1] data;
}

void main()
{
   auto obj = //make_test(20);/*
              make_test('T');//*/

  alias typ = //typeof(obj);/*
        LOG!(int, char);//*/

  "Type: ".write;

  if(isInstanceOf!(LOG, typ)/*
    is(typ : Template!Args,
    alias Template, Args...)//*/
  ) "LOG".writeln;
}
```
