def each
  @closed = false
  ## The Body must respond to +each+
  @body.each { |part|
    ## and must only yield String values.
    assert("Body yielded non-string value #{part.inspect}") {
      part.instance_of? String
    }
    yield part
  }
  ##
  ## The Body itself should not be an instance of String, as this will
  ## break in Ruby 1.9.
  ##
  ## If the Body responds to +close+, it will be called after iteration.
  # XXX howto: assert("Body has not been closed") { @closed }


  ##
  ## If the Body responds to +to_path+, it must return a String
  ## identifying the location of a file whose contents are identical
  ## to that produced by calling +each+; this may be used by the
  ## server as an alternative, possibly more efficient way to
  ## transport the response.

  if @body.respond_to?(:to_path)
    assert("The file identified by body.to_path does not exist") {
      ::File.exist? @body.to_path
    }
  end

  ##
  ## The Body commonly is an Array of Strings, the application
  ## instance itself, or a File-like object.
