There exists in the standard library a type `DictionaryLiteral` that deserves naming re-consideration before we declare ABI Stability, because it’s confusingly misnamed, being neither a Dictionary (it doesn’t provide key-based lookup of values) nor a Literal.
Instead, it’s just an immutable collection of key-value pairs you can create _from_ a literal. I’m canvassing for opinions on what it ought to be called. Some suggestions so far: - `AssociationCollection`: Following the term of art from some other languages. Slightly obscure-sounding to developers not already familiar. Also “association” and “associative” are confusingly similar, which brings back the is-this-a-dictionary problem. - `KeyValueCollection`: Problematic because key-value comes up in a totally different context in Cocoa. - `PairCollection`: “Pair” is kinda nondescript. - Do nothing. It’s not so bad. The old name can live on indefinitely via a typealias (which has no ABI consequences, so could be retired at a later date once everyone has had plenty of time to address the deprecation warnings). Removing it as not carrying its weight (and instead using `[(Key,Value)]`, which is basically what it’s a wrapper for) is probably off the table for source stability reasons. Any further thoughts welcome. _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
