Cryptic "Will Never Be Fulfilled" Warning
I am trying to understand the "Will never be executed" warning here:
protocol FatalErrorReporterInterface {
func fail(_ message: String) -> Never
}
final class FatalErrorReporter: FatalErrorReporterInterface {
// This line emits "Will never be executed" warning
func fail(_ message: String) -> Never {
fatalError(message)
}
}
Another compiler error?

Answered on Jordan Rose @Swift Evolution mailing list:
Of course it looks like me. In particular, it is similar to the SR-2729.
(I suspect this is because calling the method through the protocol generates a bit of wrapper code that then calls the original method; that wrapper code has no location of its own.)
Sorry to bother you Jordan
