What does the program print (lines separated by spaces)?

KOTLIN

enum class Light { RED, YELLOW, GREEN }

fun main() {
    println(Light.GREEN.ordinal)
    println(Light.entries.size)
}

2 3

Expecting 3 3: counting ordinal from 1. Positions start at 0, so RED is 0, YELLOW is 1 and GREEN is 2.
Expecting GREEN 3: confusing ordinal with name. name gives the text GREEN; ordinal gives its position, a number.
