"At WWDC 2015, Dave Abrahams, of C++/Boost fame and now lead of the Swift Standard Library group at Apple, introduced Swift as a Protocol-oriented language, and showed how protocols can be used to improve your code."

Lang Ext, an open-source library for C# written by London-based Paul Louth, provides a set of helper functions and types that aim to "bring some of the functional world into C#" while trying to look like extensions to the language itself.

PureScript is a strongly, statically typed language which compiles to JavaScript. It is written in and inspired by Haskell and aims at "allowing to write very expressive code which is still clear and readable" when translated into JavaScript. InfoQ has talked to PureScript creator Phil Freeman to learn more about the language.
