[swift-evolution] [Discussion] What is the future of tuples in Swift?

[Adrian Zubarev]

That’s what conditional conformances are made for in my opinion. The generics manifesto shows an example of equatable tuples iff every type is also equatable. That said, one probably should be able to extend a specific set of tuples to arithmetic operations if there is a need for that in your own project. I’m not saying that the standard library should do that, but we should have that ability to do that at some point, iff we’ll have parametrized extensions and generic variadics.
