or '' is a way to avoid syntax errors... cannot remember the exact

Perl best Practices recommends using q {}; due to readability.
$name = ($query_obj->param('text_field') or q {});
In a CGI program I wrote here is how I used it....
$q->radio_group
( -name=>'view',
-value=>[qw{All-Clients Backup-Tapes PACS-Fuji Heartlab
StreamLine-
Health Archiver-Status Tape-Drive-Status}],
-linebreak=>'true', -attributes=>\my %attributes),
$q->defaults(-name=>'Default'),$q->submit('form','Send Form'
);
my $which_radio_button = $q->param('view') || q{};
if ( $which_radio_button eq 'All-Clients' ) {
