What's happening is that the prototype tells Perl that main::new() accepts anything that might conceivably be a filehandle. The string 'CGI' certainly applies. Apparently this kind of thing is resolved before indirect method calls. (Makes sense to me, based on the locality principle.) Try, for example:

my $query3 = new STDIN;

Should that be a warning? I dunno. Is it a bug? I'm not sure. Seems like a good reason to avoid indirect object notation though, as well as prototypes. :)
