It's interesting that rails is headed toward whitespace significance in all its file formats, yet the most apparent difference between ruby and it's main rival Python is that whitespace is not significant.

Between yaml, sass (although not scss), haml, and coffescript, is the next step a version of ruby getting rid of end statements in favor of whitespace? I've often dreamed of such a thing.

  module Foo
    module Bar
      class Fubar
        def boom
          p "I like monkey patches"
        end
      end
    end
  end

Ick!
