in reply to What's the meaning of die ref $res... ?

If you feed the code you are having trouble with in to Deparse,-p you get:

C:\>perl -MO=Deparse,-p -e"die ref $res ? $res->faultstring : $soap->t
+ransport->status"
die((ref($res) ? $res->faultstring : $soap->transport->status));
-e syntax OK

And if we add a little horizontal whitespace to that:

die( ( ref( $res ) ? $res->faultstring : $soap->transport->status ) );

[download]

You can see that the ref( $res ) part is a conditional test to see if $res is a reference.

If it is, then it passes $res->faultstring to die.

Otherwise it passes: $soap->transport->status to die.
