That is more precisely what I meant. Mutters to self: "Precision of language, Ryan!" That fairly completely answers my quandary. Thank you for your time and energy.

Or would it be too opaque? _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
