def each(&block)

  # In ruby 1.9 we don't support String#each
  if @body.is_a?(String)
    yield @body
  else
    @body.each(&block)
  end

  yield @additional_text
  self
end

def respond_to?(*args)
  super or @body.respond_to?(*args)
end

#to_str ⇒ Object

In the case of to_str we don’t want to use method_missing as it might avoid a call to each (such as in Rack::Test)
