Hi lens-experts. How would I define an EnvironmentKey which may hold a subset of predefined enum values?

[Fabian Braun]

code snippet leading to the compiler err:

val enumTypes = EnvironmentKey.enum<EnumType>().multi.defaulted(
        "ENUM_TYPES",
        emptyList<EnumType>()
    )

this seems to work:

enum class Bob {
    foo, bar
}

fun main() {
    val enumTypes = EnvironmentKey.enum<Environment, Bob>().multi.defaulted(
        "BOB",
        emptyList()
    )
    println(enumTypes(Environment.from("BOB" to "foo")))
}

thank you! Great
