Greetings, I notice next() and hasNext() in Iterator are coded as operator functions (https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-iterator/index.html), but neither is documented at https://kotlinlang.org/docs/reference/operator-overloading.html or https://kotlinlang.org/docs/reference/keyword-reference.html#operators-and-special-symbols. Why is that, and are there symbols for these?
