Isn't there an annotation or something i can use to tell the compiler to smart-cast Connection to not null?

private val Connection?.isUsable get() = this != null && !isClosed

[David Cuesta]

I am not sure what is your question about, do you want a solution like this?

class Connection() {

    val isUsable: Boolean = true
    val isClosed: Boolean = true

    private val Connection.isUsable get() =  !isClosed

}
