Hmmm... that's not entirely true. There's a big difference in these two submit buttons:

<input type=Submit value="This doesn't have a value">
<input type=Submit name=Submit value="This one has a value">

In other words, if you don't provide a name, there is nothing to associate the value to. Am I missing out on something important or has everyone gone gaga? :) Also, on a side note, I'd drop cgi-lib.pl and start using CGI.pm with the compatibility mode. Ie:

use CGI;
CGI::ReadParse(*in);

My R$0.02 (its less than two cents when you convert it to US$)

#!/home/bbq/bin/perl
# Trust no1!

You are totally correct.. In my experience I generally don't see a submit input item with a name attribute unless the coder is interested in the value of the submit button..

<input type='submit' name='submit' value='Next'>
<input type='submit' name='submit' value='Previous'>

Of course you can make it whatever name you want, but if you don't particularly care what submit button they hit, just don't provide a name attribute:

<input type='submit' value='Save'>

#!/usr/bin/perl -w

use strict;
use CGI;

my $query = new CGI;
my @params = grep {$_ ne 'submit'} $query->param;

Why not use the CGI API?

#!/usr/bin/perl -w
use strict;
use CGI;
my $query = new CGI;
my $query->delete('submit');
