`max`, `count`, and `sum` are all nouns—at least in the senses they are meant in those calls—so they do not take the -ed/-ing suffixes to form immutable variants. Instead, they would take the `form` prefix to form mutable variants, if they had them. `map`, `filter`, and `reduce`—at least in the senses they must be interpreted in for the names of those calls to make sense—are verbs, and so they *would* normally take -ed/-ing suffixes. However, as broadly-accepted terms of art, we have left them alone until now. -- Brent Royal-Gordon Architechies _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
