OutcomeOfRaise

class OutcomeOfRaise(raise: Raise<Any?>) : Raise<Throwable> (source)

Emulation of context receivers, when they're released this can be replaced by context receiver based code in Arrow itself.

We guarantee that the wrapped Any? will only result in Throwable or Absent. Exposing this as Raise<Throwable> gives natural interoperability with Raise<Throwable> DSLs (Either).
