          Issue ID: 22338
           Summary: Parser rejects basic types in UDAs
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: pro.mathias.lang@gmail.com

```
@string @int
void main () {}
```

Returns:
```
onlineapp.d(1,10): Error: `@identifier` or `@(ArgumentList)` expected, not
`@int`
onlineapp.d(2,1): Error: no identifier for declarator `int`
dmd failed with exit code 1.
```

However the following compiles just fine:
```
alias SillyParser = int;

@string @SillyParser
void main ()
{
}
```

Tested with DMD v2.097.2
