Thanks for all of the help, everyone! Here's the new list_params() function:

sub list_params {
    my ( $self, $cgi ) = @_;
    my %formdata;
    $cgi = CGI::self_or_default if ( ! defined $cgi or ! ref $cgi ) an
+d $cgi;

    if ( defined $cgi and $cgi ) {
        foreach my $key ( $cgi->param ) {
            my @vals = $cgi->param( $key );
            $formdata{ $key } = _format_vals( \@vals );
        }
    } else {
        return 0;
    }
    Dumper( \%formdata );
}

It's smaller, cleaner, faster, and no typeglobs. I've tested it fairly carefully from the command line and it seems to be fine, regardless of the number of CGI objects or mixing and matching the function and object-oriented interfaces.

Wondering one thing, though: if a object is a subclass of CGI.pm. is it possible for it to not have the param() method? If so, I'll need to test for $cgi->can('param'). If it is possible to inherit from a module but not inherit all methods, how would that be done?

Cheers,
Ovid
