```D
@safe ref int wrongIdentity(ref int x) {
     return x; // ERROR! Cannot return a ref, please use "return 
ref"
}
@safe ref int identity(return ref int x) {
     return x; // fine
}
```
a keyword to return a value

``return 5;``

and a keyword to tell that a reference is returnable

``return ref int x``

that's dumb, why?
