We've generally shied away from legislating style; see our rationale behind not requiring `self.` for an example: https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160104/005478.html In languages where trailing commas are pervasively allowed, such as Perl, Python, Ruby, and modern Javascript, I haven't seen any indication that this is a major problem. Less blood has definitely been shed over it than over bracing style and other style wars. -Joe _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
