Append line numbers to the fields so I can bypass hash and array manipulation entirely. i.e item_no_1=1&item_no_2=2&item_no_3=3&qty_1=11&qty_2=12&qty_3=13)
I make heavy use of this approach with sometimes more complex 'keys'. For instance: 
use strict;
use warnings;

use CGI;
my $q = CGI::new;
# or however you get your $q ...

# input names look like "id1~id2~id3"
# or pick a delimiter you like instead of ~
for my $param ($q->param) {
    # print "$param<br/>\n";
    next unless $param =~ /.*(?:~.+){2}/;
    my ($id1,$id2,$id3) = split(/~/,$param);
    # print "$id1 - $id2 - $id3<br/>\n";
    # ...
}

(Edit: minor code addition, use strict, etc. :)

You said you wanted to be around when I made a mistake; well, this could be it, sweetheart.
