we need inline enums, please vote guys https://youtrack.jetbrains.com/issue/KT-23823

It already has a target version so looks like it's accepted already?

What would the use case of an inline enum be? Is it just for convenience factor?

And out curiosity, is there a big performance difference? They are mostly compared and used by reference, so their class-like nature shouldn't really matter much.

How would an inlined enum be represented? By their

ordinal

?

There's a bit about enums here: https://github.com/Kotlin/KEEP/issues/104

Dropped a comment in support. Here's my use case for inline enums: https://kotlinlang.slack.com/archives/C0B8L3U69/p1533092140000170

Inline enums for JS is probably good idea. We already had this discussion before, I still highly doubt that you can get any measurable performance gain comparing with Enums + EnumSet on JVM.

@karelpeeters, it looks like there is no definitive plan for inline enums, https://github.com/Kotlin/KEEP/issues/104#issuecomment-410010541
