comment: 
- !ruby/struct:SM::Flow::P 
  body: "The Forwardable module provides delegation of specified methods to a designated object, using the methods #def_delegator and #def_delegators."
- !ruby/struct:SM::Flow::P 
  body: "For example, say you have a class RecordCollection which contains an array <tt>@records</tt>. You could provide the lookup method #record_number(), which simply calls #[] on the <tt>@records</tt> array, like this:"
- !ruby/struct:SM::Flow::VERB 
  body: "  class RecordCollection\n    extend Forwardable\n    def_delegator :@records, :[], :record_number\n  end\n"
- !ruby/struct:SM::Flow::P 
  body: "Further, if you wish to provide the methods #size, #&lt;&lt;, and #map, all of which delegate to @records, this is how you can do it:"
- !ruby/struct:SM::Flow::VERB 
  body: "  class RecordCollection\n    # extend Forwardable, but we did that above\n    def_delegators :@records, :size, :&lt;&lt;, :map\n  end\n"
- !ruby/struct:SM::Flow::P 
  body: Also see the example at forwardable.rb.
