Ruby 2.0 on Rails
summary
Ruby 2.0 is slated for a February release and claims full compatibility with 1.9 while adding concrete features: refinements to localize monkey patches (examples: an RSpec-style should confined to examples, and an ActiveSupport_requirements gem that loads core extensions only inside a lexical scope), Module#prepend to replace alias_method_chain safely for method layering, Enumerator::Lazy used to implement an rcount-style file counter with low memory, and native keyword arguments handling defaults, splats and multiple hashes.
