Are there plans to return external enums in the future? This looks ugly:
Copy code
sealed external class DropEffects {
    @JsName("copy")
    object Copy : DropEffects

    @JsName("move")
    object Move : DropEffects

    @JsName("link")
    object Link : DropEffects

    @JsName("none")
    object None : DropEffects
}

In most cases such unions are open in fact
As result - const enums (new feature) will solve only half of problem

Idea suggests to use data objects. But obviously, you can't do that for external subclasses.

In described example 
objects
aren't required, 
val
is fine

You mean simple constants?

Yes, like here
Copy code
sealed external interface Align {
    companion object {
        val TOP: Align
        val LEFT: Align
        val BOTTOM: Align
        val RIGHT: Align
    }
}

We use objects only in case, when separate types are really required
One more example of constant
Which bonuses do you expect from enums in your case? Short declaration only?

DropEffects
in your example - string union emulation?

Yes. In this particular case, I think string constants will do. But it is an import from TS.
