I agree it’s worth linking to the other thread in this OP, but I disagree that “this town is too small for all of these threads” or that we as a community need to put all of our eggs in one basket or else never make any progress. I have been following the other thread and I still welcome this view on how to break down the feature conceptually.

https://forums.swift.org/t/three-steps-to-variadic-generics/33154/6 比喩が多くて賛成してるのか反対しているのかよくわからない・・・。 " I disagree ... that we as a community need to put all of our eggs in one basket" だからスレッド分けてもいいじゃないって言ってるのかな？ (edited)

And that‘s my point. You‘re proposing to push the topic forward, yet you have your own vision of this whole feature and do not consider that you could block further generalized designs. No offense though. ;)
