I find curious that this code works ```fun <T> getClass(type: T): Class<out T> { if ...

I find curious that this code works

fun <T> getClass(type: T): Class<out T> {
    if (type != null) {
        return getClass(type)
    } else {
        error("Unexpected")
    }
}
private fun <T: Any> getClass(type: T) = type::class.java

but if I inline the second method

fun <T> getClass(type: T): Class<out T> {
    if (type != null) {
        return type::class.java // Compilation error
    } else {
        error("Unexpected")
    }
}

the smart cast fails

Expression in a class literal has a nullable type 'T', use !! to make the type non-nullable
