how to change parameters of a decorator

Similar to my question about adding params to a super, I need some help on modifying the parameters of a class decorator.

I want to add some extra entries to the "x" property of the decorators first property

```
@AclPath({
x: ['foo','bar],
})
class Test {}
```

in my "parsing" code I have this

```
console.log(
classDef.getDecorator('AclPath').getArguments()[0].getText()
);
```

which gives me the text of the argument. I've tried looking at the ast viewer


looking at this, I thought that "symbol" would be the way to go ... however - if I use `getSymbol()` on `classDef.getDecorator('AclPath').getArguments()[0]` I get undefined

Is there any way of getting the arguments of `imports` and directly manipulating that ? at the moment, I'm messing about with
string manipulation which just feels dirty ;)
