The latter super non-Swifty but could easily evolve to be componentsSeparatedBySequence and rangeOfSequence. (We had some nifty attempts at this last night on #swift-lang in terms of trying to do this with reasonable speed.)
I find this a very good point and points to something interesting with Swift Foundation.
Is it more important to maintain design closely similar to Objective-C foundation, or to push for a more "swift" design philosophy that may indeed push away from Objective C foundation?
We are essentially outlining some of the foundational (no pun intended) elements of Swift, and a clean, coherent design makes sense. That said, I suspect branching away from Objective-C Foundation may create confusion for developers who write both for Apple Platforms and for servers - "Am I using Swift Foundation, or Objective-C Foundation?"
I think some clarifications on direction would be helpful here before I consider diving in and helping with Swift Foundation (which does interest me a lot!)

I'm interpreting what you wrote as that a standard library should be as flexible and widely applicable as possible while being implemented with the fewest possible moving parts ("stay focused on the lowest-level “language support” primitives")

I'm going to take a wild guess that these latter items would have to be self organizing and fall outside the umbrella of Swift and Swift-Evolution. For this bit, I'm going to defer to Kevin, etc for figuring out what would be awesome to add in.
