Detailed rationale is in the Swift Evolution proposal (https://github.com/apple/swift-evolution/blob/main/proposals/0393-parameter-packs.md https://github.com/apple/swift-evolution/blob/main/proposals...) This also isn’t a problem specific to Swift. Many strongly typed languages run into it. Examples: - C# (https://learn.microsoft.com/en-us/dotnet/api/system.tuple-8?view=net-8.0 https://learn.microsoft.com/en-us/dotnet/api/system.tuple-8?...): public class Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> - Scala (https://www.scala-lang.org/api/2.13.6/scala/Function22.html https://www.scala-lang.org/api/2.13.6/scala/Function22.html): trait Function22[-T1, -T2, -T3, -T4, -T5, -T6, -T7, -T8, -T9, -T10, -T11, -T12, -T13, -T14, -T15, -T16, -T17, -T18, -T19, -T20, -T21, -T22, +R] extends AnyRef - Java (https://www.javatuples.org/index.html https://www.javatuples.org/index.html; third party)
