Fancy is a self-hosted, dynamic, class based, pure object-oriented programming language heavily inspired by Smalltalk, Ruby and Erlang that runs on the Rubinius VM. It has first class integration with Ruby, support for asynchronous message sends, futures and actors, a simple syntax and consistent semantics, object oriented pattern matching that preserves encapsulation and much more. Fancy runs on Rubinius, a modern bytecode virtual machine designed for Ruby. It is the first fully self-hosted language running on Rubinius besides Ruby. This talk will show Fancyâ€™s semantics and language features, its integration with Ruby code, as well as how the new implementation for the Rubinius VM works and what Rubinius has to offer for programming language creators alike.
