Just published https://medium.com/livefront/sealed-enum-replacing-enums-in-kotlin-4c513e7e8db, the introduction article for https://github.com/livefront/sealed-enum!

It’s a runtime library and annotation processor that allows sealed classes of objects to completely replace normal enum classes, allowing for enumerations with base classes, generics, and hierarchies.

Too bad it's annotation processor and not compiler plugin. So only jvm is supported.

It started out internally as an annotation processor for Android projects, so the JVM limitation wasn’t an issue, but I’m definitely interested in the possibility of making it multiplatform.

A #ksp version is currently in the works and available experimentally (https://github.com/livefront/sealed-enum/pull/32), which could lead to multiplatform support.

A compiler plugin would also open up the possibility for a more integrated API by rewriting code (making the sealed class directly implement Comparable, making the companion object implement SealedEnum, etc.)
