A modern programming language that makes developers happier.

Does anybody happen to know if there’s already a bug open for this problem:

```@JsExport
sealed class Foo {
  abstract val bar: Boolean
  
  data class AFoo(override val bar: Boolean) : Foo()
}```
`AFoo` will come out with a mangled `bar`.

Oh, wow. I'm not sure, that we know about it. Could you please create the ticket?

Not exactly related, but two other issues mention similar `sealed` problems

Maybe looking at one of them will solve every one of them :eyes:
