Is there a way to transform a Raise<NonEmptyList<Error>> to a Raise<Error>?
We use the raise dsl to get config values or generate a ConfigurationError with a message. We split it up in multiple functions on Raise<NEL<ConfigError>>, but in the end I want to return a final Configuration with all subparts or raise one single Error with all the messages.
I can hardly express that with the help of lots of Eithers, but not with Raise alone.
Is there a way?

[CLOVIS]

class InputError
class OutputError(val errors: NonEmptyList<InputError>)

context(Raise<NonEmptyList<InputError>>)
fun bar() { … }

context(Raise<OutputError>)
fun foo() {
    withError(::OutputError) { 
        bar()
    }
}
