[swift-evolution] [Review] SE-0005 Better Translation of Objective-C APIs Into Swift

Why is this so important? You’re saying “this sentence”, but it’s not a sentence, and it’s not English. You can easily add the words “with” or “and” when trying to verbalize method names, but those words don't help at all in readability of code in its natural medium.

Having “options” and “locale” on the parameters side of the method call is great, but then if you make this effort, there’s no value in keeping “with”.
