outcome

inline fun <E, A> outcome(block: OutcomeRaise<E>.() -> A): Outcome<E, A>(source)

DSL build on top of Arrow's Raise for Outcome.

Uses Raise<Any?> to provide a slightly optimised builder than nesting either { option { } } and not-being able to use @JvmInline value class.

With context receivers this can be eliminated all together, and context(Raise<None>, Raise<E>) or context(Raise<Null>, Raise<E>) can be used instead.
