## Source excerpt

Heads Up This article was written waaaay back in 2018 when the current version of Kotlin was 1.2.60. At that point, inline classes were an experimental feature, and you had to explicitly opt into them. Good news! As of Kotlin 1.5, they're now a stable language feature. If you're ready to start learning about them, see the article, Introduction to Inline Classes This article is preserved only for historical context.
