We Programmers Need "Results"
> But it feels a bit weird to client side construct an Exception only to stuff it into a Result.error(...) instead of actually throwing it
yep, `kotlin.Result` constraining your error type to `Throwable` is a real headache as it forces you to still model your domain logic via exceptions. it also means people can still accidentally throw these exceptions. not to mention the overhead of creating stack traces per instantiation unless you disable that on every subclass.
i recommend using https://github.com/michaelbull/kotlin-result?tab=readme-ov-f... (which has a nice breakdown of all the other reasons to avoid `kotlin.Result`)

JEP draft: Exception handling in switch
Author here. I have no idea what you could possibly mean with this comment. The coroutineBinding implementation correctly uses the coroutines API for parallel decomposition of Result bindings, exactly how the Kotlin Corotines guide tells you to (backed by a [Mutex](https://github.com/michaelbull/kotlin-result/blob/master/kot...)). The coroutineBinding isn't even the main selling point of the library, you can use it without using this feature entirely.
Please could you elaborate on what "looking thread safe" means to you? The only portion of the library that supports concurrency *is* thread safe - the unit tests prove it and the use of concurrency primitives such as Kotlin's Mutex are indicative of this. I truly have no idea how you've judged the entirely of the lbirary on whether it's "thread safe" when there is a single function that's related to concurrency and it is very clearly using concurrency primitives.

How do you define errors?
Sealed classes in combination with a library like https://github.com/michaelbull/kotlin-result will get you what you need. Essentially at that point you'll be doing error handling the way you would in Rust, where a 1-level deep sealed class containing data classes as children act as the root error type and each of its variants. If you have errors coming from two different domains you just create a wrapper error type for each domain.

Is runCatching in use in any of your projects ? My team is abusing it
Lastly I do not like kotlin's Result and we use the kotlin-result library which is more expressive and not tied to Throwable (similar to Arrow's Either).

Struggling with software robustness with Kotlin
In my own code, I started to use explicit error handling. I'm currently experimenting with Result (from https://github.com/michaelbull/kotlin-result) and Raise (from https://arrow-kt.io/).

Thoughts on Kotlin Multiplatform?
un-related to multiplatform i've found it extremely helpful to wrap things in a Result type. If something can throw an error, it get's a Result return type. It sounds like that would help your use case too. The built in Result may be useful too

Programming with Result
This is a better impl.
- It seems like I'm forced to make this choice at least once a day
