In addition the proposal would result in eliminating a commonality of `case` clauses allowing a `where` clause everywhere except in conditional clauses which is worse. I'd much rather prefer to drop the commonality with var/let declarations! -Thorsten _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
