hash syntax

hash.rb

class Hash
  def id
    self["id"] || self[:id]
  end
  def type
    self["type"] || self[:type] || self.type
  end

  def method_missing(meth, *args, &block)
    if args.size == 0
      self[meth.to_s] || self[meth.to_sym]
    else
      if meth.to_s.end_with?("=")
        value = meth.to_s.chomp("=")
        self[value] = args[0]
      end
    end
  end
end

allows one to write:

a = {}
a.x = 1
