As others have mentioned, the interesting thing in this space is language support for regex literals.  They should tie into the pattern matching constructs in the language (e.g. switch, if case, etc).

Better support for JSON is also interesting and possible over the next year, but it would be the domain of the corelibs folks.  I believe they have some ideas in this space, but probably aren’t ready to dive into it given that Swift 3 isn’t done, and I’m not sure if there are any “plans”.
