How should I return multiple const values from a function?

My mistake, I forgot that enum cannot be inferred!

Very very sorry, suppose I didn't intervene 😀 Also this has 
worked:

```d
void main() {
   template Fun(Key, Value)
   {
     import std.typecons;
     alias Tup = Tuple!(const(Key), const(Value));
     enum Fun = (Key k, Value v) => Tup(k, v);
   }

   string k;
   uint v;

   auto res = Fun!(string, uint)(k, v);

   assert(
     is(typeof(res[0]) == const(string)) &&
     is(typeof(res[1]) == const(uint))
   );
}
```
