How do I make this compile?

sealed class InputSelection<T> {
    object None: InputSelection<T>()
    data class Some<T>(val value: T): InputSelection<T>()
}

I tried with

sealed class InputSelection<T> {
    object None: InputSelection<Nothing>()
    data class Some<T>(val value: T): InputSelection<T>()
}

but then I can't use InputSelection.None where I'm expecting an InputSelection<T>
