Isn't there EnumSet.of already in the Java standard library?

[jw]

Kotlin runs on more than Java!

[karelpeeters]

Right, I've been trying out Kotlin-JS for a while now and I still seem to forget 🙄.

[jw]

you can't mostly use setOf, but the all case isn't covered

[karelpeeters]

setOf(*MyEnum.values()), could be cleaner of course.

[karelpeeters]

(I believe you've made a typo)

[jw]

true

[jw]

so maybe it's all covered

[jw]

MyEnum.values().toSet()

[kevinmost]

but doesn't that just return you a Set, not an EnumSet? Wouldn't you want some specialized version that gives you the EnumSet?

[jw]

I don't really care that much. I assumed an enumSetOf would just delegate to a normal set on JS or native to start with.

[kevinmost]

Hm, I assume as much too. But wouldn't it be nice to have a method that, when called on JVM, gives you a nice efficient EnumSet, and when called elsewhere, gives you just a normal Set? Maybe setOf could check if the elements it's being passed are `Enum`s and make an EnumSet if so. But that doesn't cover the case of creating an empty mutable set, of course
