For the future, I think I remember context will work on the primary constructor, so will something like this work?

sealed class PasswordValidationError {
    object TooShort : PasswordValidationError()
}

value class Password context(Raise<PasswordValidationError>) constructor(val text: String) {
    init {
        ensure(text.length > 8) { PasswordValidationError.TooShort }
    }
}

AFAIK this should indeed work, but note that it might missbehave with KotlinX Serialization. I am not sure how it deals with CancellationException, I know it wraps some exceptions but I haven't looked deeply into it.

Ah, you're right this might be an issue.

If it turns out to be problematic, I would still just use require and do something like this: https://github.com/nomisRev/ktor-arrow-example/blob/2ec99199bee7c80633834450f811ff1610a3cfd0/src/main/kotlin/io/github/nomisrev/routes/users.kt#L105

catchOrThrow is in line with reified Raise.catch but for Either 😉

Ah, that does sound like a good idea
