I could try and implement lots of operator overloads but I think that could be potentially buggy and not so NFC-like. @compnerd you wanted to leave the OBJC_PR_  and dropped the DQ prefixes right? Other than that, ping (for others)? I think this could be a nice cleanup. 
If you just want the scoping benefits of the enum class you can simulate it with a `namespace`:

```
namespace ObjCPropertyAttribute {
enum {
  noattr,
  readonly,
  ...
};
}
```

Which would make the users of this enum look a bit nicer. I agree that adding overloading operators is over-engineering this.
