Hi, I am handling errors in SOAP::LITE with the help of http://guide.soaplite.com/#error%20handling It works as I need, but I am stuck trying to understand this block of Perl code: 
on_fault => sub { my($soap, $res) = @_;
    eval { die ref $res ? $res->faultstring : $soap->transport->status
+ };
    return ref $res ? $res : new SOAP::SOM;
  };

[download]
Specially, after it dies, I do not understand the meaning of ref $res ? $res->faultstring : $soap->transport->status Is it referencing or something?

Any didactic help will be really appreciated.

Regards
