[swift-evolution] [Pitch] Introducing the "Unwrap or Die" operator to the standard library

[Erica Sadun]

Using an operator to provide feedback on the context of a failed unwrap has become a commonly implemented approach in the Swift developer Community. What are your thoughts about adopting this widely-used operator into the standard library?

guard !lastItem.isEmpty else { return }
let lastItem = array.last !! "Array must be non-empty"

Thank you for your thoughtful feedback, -- E
