Is there a way to declare in a base class that a function either takes a List<String> or a Sequence<String> and than in an override decide if you get the List or the Sequence? Or is this just overengineered and I should always take a Sequence ?

I have this in my base class

val input: Sequence<String> = // ...
val cachedInput: List<String> by lazy {
    input.toList()
}

Subclasses can use either. Both over- and under-engineered 😄

Hm how do you then choose between test and real input?
