Redirect does not terminate the response, which may be confusing

I got caught by surprise that redirect doesn't terminate the response. Added myself a redirect! like so, but maybe this needs to at least be documented or an option added to stop the response:

module Grape
  module Extensions
    module RedirectExtension
      def redirect!(url, options = {})
        redirect url, options
        throw :error, status: @status, headers: @header
      end

      Grape::Endpoint.send(:include, self)
    end
  end
end

Start by locating Grape's redirect implementation and the response termination path; the issue does not name files or tests. Compare the current redirect behavior with the proposed RedirectExtension example, then establish whether the accepted outcome is documentation or an optional terminating redirect and add coverage showing when the response stops.
