Enums with custom implementation

1

The code 

enum class Alphabet{
    A{
        var str: String = "Dzien dobry"
    },
    B,C,D
}

The usage 

println(Alphabet.A.str)  //this one fails to compile as property "str" is unknown
println((Alphabet.A as Alphabet.A).str)  //awkward cast makes it work

It's not that it crashes or something but still kinda strange when one reads such code

It's a bug: the type Aplhabet.A should be private to itself so that the "awkward cast" is illegal.

Do you mean that accessing Alphabet.A.str will not be possible any more?

Exactly.
