what about iterator() on `Enum`s, so that we can write for(e in enum)? Instead of e in enum.values() which, I guess, implies an array copy?

There's no safe way to iterate enum elements without copying.

(sun.misc.SharedSecrets is not a safe way :)

I didnt know that, thanks for sharing it, Mike!

anyway, if an enum is supposed to be immutable, why dont expose it?

[miha-x64]

Arrays cannot be immutable on the JVM.
I think returning $VALUES.clone() was a mistake, and it should be public static final Set<Self> VALUES = unmodifiableSet(EnumSet.allOf(Self.class)) instead.
