If you execute

```
writeln( "'Counter' is ", &Counter );
```

It shows the Counter address:

```
'Counter' is 557F2567F940
```

Not the function signature like it does with ```next```


I propose a simple change:

```d
void main(){
   auto Counter = (int nextValue) => () => nextValue++;
   auto next = Counter(10);
   writeln( "'next' is ", next );
   writeln( "'Counter' is ", Counter );
}
```

first ```writeln``` shows the signature of next:
```
'next' is int delegate() pure nothrow @nogc @safe
```

second writeln shows the address of Counter
```
'Counter' is 55568953C910
```

- Why writeln doesn't treat ```next``` and ```Counter``` the same 
way?  (I think I understand why, but it shows a "low" level 
difference of something that syntactically is equivalent)

- What is the way to show Counter signature using ```writeln``` 
(if possible)?
