  value = storage.objectForKey storage_key(key)

  # RubyMotion currently has a bug where the strings returned from
  # standardUserDefaults are missing some methods (e.g. to_data).
  # And because the returned object is slightly different than a normal
  # String, we can't just use `value.is_a?(String)`
  value.class.to_s == 'String' ? value.dup : value

.[]=(key, value) ⇒ Object
