This [has already been discussed here](https://discuss.kotlinlang.org/t/property-with-different-public-signature-than-private/10590) and there is [an open issue for this](https://youtrack.jetbrains.com/issue/KT-14663) (KT-14663).

At the moment, the second workaround:

```kotlin
val addressList: List<String> get() = _addressList

```

would (IMO) be more idiomatic than a function.
