Would union types in Kotlin, instead of overloads be possible in the future?

[Ruckus]

I believe #arrow-meta has done some work in that regard, but I doubt it will make it into the language itself.

You can emulate this with sealed classes, but this doesn't work well because you'd have to intrusively add inheritance to the types in question

There's a proposal to allow for interface inheritance to be added non intrusively, once that's available it would be possible to emulate this in a rather verbose but decent way
