You mean presenting in evaluate method? I could parse column value like

```
type.toBytes(type.toObject(ptr, expression.getColumnModifier()), expression.getColumnModifier());
```

(on line 67) if it would be better. Our use case is to already have hex values stored in column, so query like this won't be necessary. But if you thing is nice to have, can you please tell me more about functions you thinking about? I think I didn't found any particular in other built in functions.
