          Issue ID: 24848
           Summary: bad parser diagnostic for a partial MulExp
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: diagnostic
          Severity: minor
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: b2.temp at gmx.com

given the wrong code:

```
module runnable;

void main()
{
    struct A1 {}
    if (A1*) {}
    return;
}   
```

you get the error messages

> /tmp/temp_7FA97E5E13D0.d(6,12): Error: expression expected, not `)`>
> /tmp/temp_7FA97E5E13D0.d(6,14): Error: missing closing `)` after `if (A1 * 0`

The second message is very bad. First it does not output the input. In no way
we multiply by zero. Second the closing right paren is there.
