 # #record_number(), which simply calls #[] on the <tt>@records</tt>
 # array, like this:
 #
-#   require 'forwardable'
-#
 #   class RecordCollection
-#     attr_accessor :records
 #     extend Forwardable
 #     def_delegator :@records, :[], :record_number
 #   end
 #
-# We can use the lookup method like so:
-#
-#   r = RecordCollection.new
-#   r.records = [4,5,6]
-#   r.record_number(0)  # => 4
-#
 # Further, if you wish to provide the methods #size, #<<, and #map,
 # all of which delegate to @records, this is how you can do it:
 #
-#   class RecordCollection # re-open RecordCollection class
+#   class RecordCollection
+#     # extend Forwardable, but we did that above
 #     def_delegators :@records, :size, :<<, :map
 #   end
+#   f = Foo.new
+#   f.printf ...
+#   f.gets
+#   f.content_at(1)
 #
-#   r = RecordCollection.new
-#   r.records = [1,2,3]
-#   r.record_number(0)   # => 1
-#   r.size               # => 3
-#   r << 4               # => [1, 2, 3, 4]
-#   r.map { |x| x * 2 }  # => [2, 4, 6, 8]
+# If the object isn't a Module and Class, You can too extend Forwardable
+# module.
 #
-# You can even extend regular objects with Forwardable.
-#
-#   my_hash = Hash.new
-#   my_hash.extend Forwardable              # prepare object for delegation
-#   my_hash.def_delegator "STDOUT", "puts"  # add delegation for STDOUT.puts()
-#   my_hash.puts "Howdy!"
+#   printer = String.new
+#   printer.extend Forwardable              # prepare object for delegation
+#   printer.def_delegator "STDOUT", "puts"  # add delegation for STDOUT.puts()
+#   printer.puts "Howdy!"
