A modern programming language that makes developers happier.

I'm writing type defs and came across
```{GridCoordinates2D|HexagonalGridCube2D|Point} HexagonalGridCoordinates2D```
and wondered, if there was a way to model that in Kotlin. Couldn't you use a marker interface for that? As in: an empty interface that all of these types extend?

Is that a union type?
If it is, there is no direct translation. You can play with overloads if it's a parameter, or have - as you suggested - a sealed interface with multiple extenders. But then you still need a way to discriminate.

If it’s union - pill depends on use case.

union type yes; just found out that finding a common super class is probably impossible

used in multiple ways; but overload is going to work, thank you

but that's better for type safety than passing the wrong stuff to the constructor
