Какое количество экземпляров класса Nothing допустимо в рамках одного приложения?

In the Kotlin language (often used for Android), the Nothing class is a special type that has no instances. It is used to denote functions that never return a value (for example, they always throw an exception or run infinitely).

Therefore, within a single application, the number of instances of the Nothing class is zero — it is impossible to create an object of this type.

Example of usage:

fun fail(message: String): Nothing {
    throw IllegalStateException(message)
}

Here, the fail function returns Nothing, which means it will never complete normally.
