[swift-evolution] [Discussion] Enforce argument labels on tuples

[Tino Heth]

I think it's good that the labels aren't enforced:
This would sacrifice flexibility, and force us to write unnecessary boilerplate to "translate" labels (one library might use (height, width), and another (h, w) to express the same concept…)

But: Objective-C had no tuples, so a final decision shouldn't happen until there is an agreement on best-practices for them...
