module SugarCube
  # A subclass of Hash that allows its keys to be accessed and assigned by
  # method name.  Useful to quickly mock objects.  To that end, a
  # `NoMethodError` is raised anytime the key doesn't exist (getter or setter)
  #
  # You can convert an existing Hash or NSDictionary into a Anonymous using the
  # constructor `SugarCube::Anonymous[hash]`, or you can call `to_object` on a
  # dictionary or hash.
  #
  # @example
  #     obj = {
  #       'first_name': 'Katsuyoshi',  # strings
  #       company: 'Ito Soft Design',  # and symbols are supported
  #     }.to_object
  #
  #     obj.first_name
  #     # => 'Katsuyoshi'
  #     obj.company
  #     # => 'Ito Soft Design'
  #     obj.bla  # => raises NoMethodError
  #     obj.bla = 'bla'  # => raises NoMethodError
