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

[Rien]

I would not use it.
Somehow it gives me the creeps to leave something like ‘fatalError’ in a shipping application.
During development it could make sense, but then again I like to keep development and shipping the same as much as possible.

Regards,
Rien
