Varnish redirect operation to easy(libvmod-redirect)

Varnish redirect is pain.

sub vcl_recv {
  if (req.http.user-agent ~ "iP(hone|od)") {
    error 750 "Moved Temporarily";
  }
}

sub vcl_error {
  if (obj.status == 750) {
    set obj.http.Location = "http://www.example.com/iphoneversion/";
    set obj.status = 302;
    return(deliver);
  }
}

(via:Redirecting using VCL)
I just want to redirect. but should write code in two action.
This is it lack of maintenance, and I do not like.
I tried to make a vmod_redirect can be easily redirect.

If you do the same thing and just

import redirect;
sub vcl_recv {
   if (req.http.user-agent ~ "iP(hone|od)") {
      error(redirect.location(302,"http://www.example.com/iphoneversion/") , "Moved Temporarily");
   }
}

If you do not need reason phrase

import redirect;
sub vcl_recv {
   if (req.http.user-agent ~ "iP(hone|od)") {
      error(redirect.location(302,"http://www.example.com/iphoneversion/"));
   }
}

note:require enclose in error method.
