Comment (by falconindy):

 For some reason I thought I was finished porting... More examples:

 - obj.status -> beresp.status (in vcl_backend_error)
 - obj.response -> beresp.reason (in vcl_backend_error)
 - in vcl_hash, return(hash) is no longer valid
 - in vcl_pass, return(pass) is no longer valid
 - in vcl_recv, return(lookup) is no longer valid

 A bunch of this seems to be inferred by the builtin.vcl shipped with
 varnish.
