-    module ClassMethods
-      # Adds reader and writer methods for manipulating a value object:
-      # <tt>composed_of :address</tt> adds <tt>address</tt> and <tt>address=(new_address)</tt> methods.
-      #
-      # Options are:
-      # * <tt>:class_name</tt> - Specifies the class name of the association. Use it only if that name
-      #   can't be inferred from the part id. So <tt>composed_of :address</tt> will by default be linked
-      #   to the Address class, but if the real class name is +CompanyAddress+, you'll have to specify it
-      #   with this option.
-      # * <tt>:mapping</tt> - Specifies the mapping of entity attributes to attributes of the value
-      #   object. Each mapping is represented as an array where the first item is the name of the
-      #   entity attribute and the second item is the name of the attribute in the value object. The
-      #   order in which mappings are defined determines the order in which attributes are sent to the
-      #   value class constructor.
-      # * <tt>:allow_nil</tt> - Specifies that the value object will not be instantiated when all mapped
-      #   attributes are +nil+. Setting the value object to +nil+ has the effect of writing +nil+ to all
-      #   mapped attributes.
-      #   This defaults to +false+.
-      # * <tt>:constructor</tt> - A symbol specifying the name of the constructor method or a Proc that
-      #   is called to initialize the value object. The constructor is passed all of the mapped attributes,
-      #   in the order that they are defined in the <tt>:mapping option</tt>, as arguments and uses them
-      #   to instantiate a <tt>:class_name</tt> object.
-      #   The default is <tt>:new</tt>.
-      # * <tt>:converter</tt> - A symbol specifying the name of a class method of <tt>:class_name</tt>
-      #   or a Proc that is called when a new value is assigned to the value object. The converter is
-      #   passed the single value that is used in the assignment and is only called if the new value is
-      #   not an instance of <tt>:class_name</tt>. If <tt>:allow_nil</tt> is set to true, the converter
-      #   can return nil to skip the assignment.
-      #
-      # Option examples:
-      #   composed_of :temperature, mapping: %w(reading celsius)
-      #   composed_of :balance, class_name: "Money", mapping: %w(balance amount),
