How can I access ::class of a nullable reference?
I can do it this way: nullableVal?.let { it::class }
but I would like to know if there is a shorter version. It's a shame I can't just nullableVal?::class instead, like I can with nullableVal?.javaClass 😅

You could write extension property. Smth like this:
val Any?.klass : KClass?
get() = if (this == null) null else this::class

Thanks for the tip. I was wondering if anything similar is already in the stdlib though 🙂

Technically, there's ?.javaClass?.kotlin but that's definitely kinda goofy-looking
