Subject: Confusion with Forwarrordable#delegate - throwing an er

require 'forwardable'

class MyQueue

  extend Forwardable
  attr_reader :queue

  def initialize
    @queue = []
  end

  def_delegator :@queue, :push, :mypush

end

q = MyQueue.new

q.instance_delegate [:clear, :first] => @q
#`<main>': undefined method `instance_delegate' for #<MyQueue:0x2119e48
@queue=[]> (NoMethodError)

q.delegate [:clear, :first] => @q

#`<main>': undefined method `delegate' for #<MyQueue:0x2109e40
@queue=[]> (NoMethodError)


Can you tell me what wrong I did? How to fix that?
