Umar, where did you see that inline classes are coming soon? Or is that just based on the some of the discussions about inline classes starting in 2013? [What are inline classes](https://discuss.kotlinlang.org/t/what-are-inline-classes/6599), [Implicit conversions between type aliases](https://discuss.kotlinlang.org/t/implicit-conversions-between-type-aliases/3222), [Extension Functions on Type Aliases Should only Be Accessable From Similar Types](https://discuss.kotlinlang.org/t/extension-functions-on-type-aliases-should-only-be-accessable-from-similar-types/3722)
