A modern programming language that makes developers happier.

kotlinlang

I just read carefully what's new in 1.7.0 and after seeing <https://kotlinlang.org/docs/whatsnew17.html#allow-implementation-by-delegation-to-an-inlined-value-of-an-inline-class|"Allow implementation by delegation to an inlined value of an inline class">, I wonder if it would be possible to do the same for (abstract) classes.
In this way, unsigned numbers could extend the abstract class `Number`
```@JvmInline
public value class UInt @PublishedApi internal constructor(@PublishedApi internal val data: Int) : Comparable&lt;UInt&gt;, Number by data```
and I'd be super happy because I don't have to create tons of additional and redundant constructors and methods specifically for every single unsigned (in <https://github.com/kotlin-graphics/glm|glm>)

We can do it in the future. We’ll need to introduce a concept of `abstract value class` and make Number one of them. 

is there a ticket to follow? If no, would you like me to create one?

There is no issue for this particular use-case, but <https://youtrack.jetbrains.com/issue/KT-34217/Consider-introducing-mechanism-for-inline-classes-to-override-methods-from-Any-identically|https://youtrack.jetbrains.com/issue/KT-34217/Consider-introducing-mechanism-for-inline-classes-to-override-methods-from-Any-identically>
