I’m going to leave a lot of this for Ted, but I want to underline something I said in the proposal: it has always been a goal for Swift to enable libraries that feel clean and fluent at the point of use, and the team has always felt that there was a place for eDSLs in Swift. Three days after we announced Swift, I got up on stage at WWDC and spent ten minutes explaining how you could use various features in Swift to build a nice eDSL for writing text adventures; of course that was expository, but it was also earnest: if these things make your code better, if they solve problems for you without creating bigger ones, then you should use them and not feel ashamed. I think we’re all aware that that’s not to everyone’s taste, but it’s part of our basic design philosophy, not something being forced on us by political demands.
