```
open class Base<T> {
fun foo(): T = ...
}
class Derived<T> : Base<T> {
override fun foo(): T = ...
}
```
In intersection scope of type `Base<T> & Other<R>` we should create
intersection override based on `Base.foo(): T` and `Derived.foo(): R`
at the same time, despite the fact that `Derived.foo` actually directly
overrides `Base.foo`
