Hey there!
Let’s imagine I have the following code in Android application (but the platform doesn’t matter):
```val anim = if (Random.nextBoolean()) LinearOutSlowInInterpolator() else FastOutSlowInInterpolator()```
`LinearOutSlowInInterpolator` and `FastOutSlowInInterpolator` are contained in Java library (actually android.jar) and have the same package-private super class `LookupTableInterpolator` . So inferred type of `anim` value is `LookupTableInterpolator`.

I wonder why the compiler generates a warning instead of en error that `LookupTableInterpolator` is inaccessible in this context. Because the code from above is compiled successfully but always fails at runtime. Is it possible to treat such warnings as errors?
