Hi everyone. I have a question about Kotlin Unsigned types, which are still marked as experimental language feature. Do you think they are feasible for use in a multiplatform Android/iOS project using shared module written Kotlin Native? Thanks.

Implementation of unsigned types heavily depends on inline classes feature. Namely, each unsigned class is actually an inline class, which uses the signed counterpart value as a storage.
Is this good or bad for your use case? :)

Well, I have used unsigned types until now on Kotlin/JVM and now I wanted to ask if porting same code to Kotlin/Native and compiling it for iOS target will work well. I mean - I can test it myself if it will work but I was curious about some hidden implications of usage Unsigned types on iOS.
