A modern programming language that makes developers happier.

kotlinlang

I remember a related kotlin discussion but any progress/plans to inherit arguments in a concise manner? This is awfully verbose:
```
sealed class DialogState(open val title: String, open val text: String) {
    data class ConfirmDelete(override val title: String, override val text: String) : DialogState(title, text)
    data class CantDelete(override val title: String, override val text: String) : DialogState(title, text)
}
```

Well you can start by removing `open` and `override val`

and trying to invent names that doesn't conflict with default ones? Like `title1`, `title2`? :simple_smile:  I wouldn't call it an improvement.

I prefer abstract properties in this case, doesn't require passing them to constructor or DiapogState

Not perfect, but imo better and already works

```sealed class DialogState { 
   abstract val title: String
   abstract val text: String

    data class ConfirmDelete(override val title: String, override val text: String) : DialogState()
    data class CantDelete(override val title: String, override val text: String) : DialogState()
}
```

Also this allow to avoid unnecessary field when you want to use getter instead of property in one or child classes

<@U0N8HQET0> if you follow <@U0GSLCF1D> suggestion, you don't need to invent names.

The subclasses take a parameter, rather than defining a property by removing override val. Just have ConfirmDelete(title:String, text:String): DialogState(title, text). And DialogState only needs val on property to expose in all.

No need for override. No need for unique names as the function parameter doesn't conflict with the inherited property.

data classes require properties, so it won't work. You'd need to content with regular classes and for me it's undesirable.

Ahhh. Missed that detail.  Sorry about that. Thus far I haven't needed a sealed class to be a data class as I've never compared them or used them as keys in a map or similar. 

abstract property is what I ended up using, it still boggles my mind that I type the same names in 3 places instead of one. Was trying to see what other languages do, but didn't find an example of a better syntax to propose :neutral_face:
