in reply to warningsToBrowser

Someone complained about not being able to use "fatalsToBrowser", so here is a quick cut-n-paste way of getting both: 

{
    my( $warn, @warns );
    BEGIN {
        $warn= sub {
            my( $head, $tail )= ( @_, "", "" );
            if(  @warns  ) {
                print "\n$head<p>Warnings:<pre>\n",
                    @warns, "</pre></p>$tail\n";
                @warns= ();
            }
        };
        $SIG{__WARN__}= sub {
            push @warns, $_[0];
        };
        $SIG{__DIE__}= sub {
            print "Content-Type: text/html\r\n\r\n",
                "<html><head><title>Fatal error</title>\n",
                "</head><body>";
            &$warn();
            print "<p>Died because:\n<pre>$_[0]</pre></p>",
                "</body></html>\n";
            exit 0;
        };
    }
    END {
        &$warn( "<html>", "</html>" );
    }
}

Note that this breaks eval like old versions of CGI::Carp, so install a good version of CGI::Carp to fix that problem. (:
