I need to make an enum for android ApplicationInfo flags:

enum class PackageFlags(val mask: Int) {
	NONE(0), SYSTEM_APP(1), IS_DEBUGGABLE(2), SYSTEM_APP_UPDATED(128), IN_SD_CARD(262144),
	IS_DATA_ONLY(16777216), IS_STOPPED(2097152)
}

Take in account that if you use enums intensively and you need performances, you should use `Int`s instead

EnumSet

But I thought the whole point of enumset was for performance with its backing bitwise storage of enums? Whereas regular kotlin enums create a new class for each instance. Or maybe enumset does too when wrapping a kotlin enum?

No, the point of using

EnumSet

is that readability, usability and safety is increased, because the

EnumSet

type explicitely specifies which kind of enumrators expect. But to have this, you pay something in performances (nothing is fastest than using simple `Int`s)

Not just a couple!!! Tons! 😮 I guess I got the right person for this 🙂
