    # This module contains the logic for the response callbacks.
    # The on_complete callback is the only one at the moment.
    #
    # You can set multiple callbacks, which are then executed
    # in the same order.
    #
    #   easy.on_complete { p 1 }
    #   easy.on_complete { p 2 }
    #   easy.complete
    #   #=> 1
    #   #=> 2
    #
    # You can clear the callbacks:
    #
    #   easy.on_complete { p 1 }
    #   easy.on_complete { p 2 }
    #   easy.on_complete.clear
    #   easy.on_complete
    #   #=> []

      #

      #   request.on_complete { p "yay" }
      #
      # @param [ Block ] block The block to execute.
