Can I have overridden

val

fields in an enum? Something like this? Or do I have to refactor them into getters?

enum class Foo {
    abstract val bar: String
    FIRST { override val bar = "FIRST BAR" }
    SECOND { override val bar = "SECOND BAR" }
}

is there a specific reason you can’t have the value in the constructor?

enum class Foo(val bar: String) {
  FIRST("FIRST BAR"),
  SECOND("SECOND BAR"),
  ;
}

no, that's a great idea; I'll do that. More generally, just because I'm curious, is there a reason my first example won't work? Maybe something dumb I'm doing with the syntax?

Yes, put the abstract property after the

which follows the enum constants.

enum class Foo {
    FIRST { override val bar = "FIRST BAR" },
    SECOND { override val bar = "SECOND BAR" };
    abstract val bar: String
}
