Much Ado About CoffeeScript

" summary

Claims that Rails 3.1 adopts CoffeeScript as the asset-pipeline default and shows concrete install and integration steps: node.js plus npm install -g coffeescript, editor bundles for TextMate/vim/emacs, and placing files under app/assets/javascripts/.js.coffee. Demonstrations show CoffeeScript compiling down (it compiles to JavaScript*), concrete syntax rewrites (->, @, indentation), ten notable features (classes, lexical scoping, existential operator, splats, comprehensions) and examples of Rails integration and generated output so viewers can judge usefulness.
