so use x as? y != null

Are you interroping with Java at all? If you just use Kotlin, is can compare against nullable types.

val x: String? = null
    
    println(x is String) // false
    println(x is String?) // true

Hmm thing is I don't have objects, I have an object and a type, but I'm working with KClass<Any> instances, which i can't use in both sides of the is operator

Came up with this in case you'll need it 😄
Edit: That was wrong, better way

infix fun <T : Any> KClass<out Any>.instanceof(clazz: KClass<T>): Boolean {
    return try {
        this as T
        true
    } catch (e: ClassCastException) {
        false
    }
}

Might as well make that reified
