It's the most wonderful time of the year again... the time when the Swift community considers adding a Result type to the standard library. Except that this time it'll probably work!

68: Opaque Result Types

In this episode, Jesse and JP dive in to opaque result types, which could help prevent leaking of implementation details to library consumers.
