Does D 2.110 support named parameters?

[Richard (Rikki) Andrew Cattermole]

It compiles with dmd 2.109.1 if other problems are solved.

```d
void main() {
     string[string] dictionary = [
         "blue": "mavi",
         "red": "kırmızı",
         "gray": "gri"
     ];

     printAA("Color Dictionary", dictionary, commaSeparator: "\n");
}

void printAA(string title, string[string] aa,
     string keySeparator= ": ",
     string commaSeparator = ", ") {
}
```
