def accepts_definitions(*accepts)
  @own_dictionary = own_dictionary.merge(AssignmentDictionary.create(*accepts))
end

#define(&block) ⇒ Object

Prepare the defintion for an instance of this class using its definitions. Note that the block is not called right away – instead, it’s deferred until one of the defined fields is needed.
