Why did Kotlin choose value class/inline class to implement Result instead of normal sealed class and data class inheritance?

[Chilli]

Not sure if that's the case but inline classes can be used to avoid overhead due to additional heap allocations

[Marc Knaup]

Yeah, performance. Result is used in a lot of hot coroutines code. Always creating a real Java object would incur significant overhead.
