Are there any plans to make all number types (including unsigned ones) implement a shared interface?
It’s odd to that unsigned numbers don’t implement `kotlin.Number`, which unfortunately is an abstract class.

they should change that to `interface`  if possible

They don't implement a shared type on the jvm, and since kotlin interfaces map directly to java interfaces, the only way to do this would be using something like typeclasses (<https://github.com/Kotlin/KEEP/pull/87|https://github.com/Kotlin/KEEP/pull/87>)
