I’ve learned Kotlin just one month ago. So I still have many gaps. I know that there are nesting function in Kotlin, unfortunately getToken will be used in other constructs like expression evaluators. With is a really nice feature in Kotiln, remember me a little be with statement in Pascal. I confess that for me, an old school programmer very familiar with functional programming, it’s a little bit unreadable for me some nice features from Kotlin.
