Is it possible to type function arguments as @serializable or having some annotation?

Do you want it for a compilation error? Instead of finding out later at runtime

If there were a way, I'd assume e.g. Json.encodeToString(value) would've use it. Technically though anything could be serializable depending on the Json instance's serializersModule, so it's a little fuzzy what actually counts as serializable, and is also out of reach from the type system because it's configurable.

In the past (especially for testing) I've used a simple SerializableValue class, passing around the value bundled with its serializer. It can be a bit obtrusive though depending on what you're doing.

data class SerializableValue<T>(
    val serializer: KSerializer<T>,
    val value: T
)

That makes sense, thanks.
