A modern programming language that makes developers happier.

kotlinlang

I have started to explore how <https://github.com/WebAssembly/component-model/blob/main/design/mvp/WIT.md|WIT> translates to Kotlin <https://github.com/sdeleuze/kowasm/blob/main/component-model/src/wasmTest/kotlin/org/kowasm/componentmodel/WitToKotlin.kt|here>, I would be interested to have feedback especially on the various open questions identified as TODO in the code and summarized below:
• Confirm multiple named return values requires the creation of a dedicated data class.
• Does WIT `result` function return value translate for most use cases to returning an unwrapped return value + throwing an exception in case of error?
• How Kotlin properties mutability should be inferred from WIT?
• Is it idiomatic to translate WIT flags as data class of `Boolean` properties?
• How WIT `union` should translate to Kotlin?
