## test case

```d
void main()
{
    int a;
    (auto ref () {return a;}()) = 0; // OK
    auto ref () {return a;}() = 0;   // NG
}
```

## output

(many parser errors)

## notes

- Only observed for the 3rd rule (https://dlang.org/spec/expression.html#function_literals). - Must be that the parser takes the path of a declaration,
