in reply to How do I get at the parameters in my CGI program?

As contributed by icuc:
use strict;
use CGI;
# .....
my $q = new CGI;
my %params = {};
{
  my @params_names = $q->param;
  for(@params_names) {
    $params{$_} = $q->param($_);
  }
}

or, a shorter way, as contributed by slayven:

use CGI;
my $q = new CGI;
my %in = map { $_ => $q->param($_) } $q->param;

    Lincoln Stein no longer recommends the use of the visible CGI object, simply because the number of CGI objects in a typical program is merely one. Instead, pull in the methods you need as subroutines. If parameter access is all that's required, use: 
    use CGI qw(param);
...
my $source = param('source');
my @destination_states = param('dest'); # multi-select

    But I typically use 
    use CGI qw(:all);

    since I'm also using the HTML generation shortcuts.
