I'm trying to write a some code which prints out every defined variable in my program. (I'm debugging a giant program which uses hundreds of global variables and I think this would be useful.) I can iterate over %main and see everything in it, but I don't see my'd variables even when they're in my current scope.

Are my'd variables kept in some other place?

Here's my code. I thought it would at least print out $symname and $shouldPrint. Ideally I'd like to also see @colors2 and $symbols, but I suspect that shouldn't be possible. 

use Data::Dumper;

$joe = 1;
$matt = 2;
@colors = ('tan', 'silver', 'silver', 'green', 'black');
my (@colors2) = ('red', 'green', 'blue');
my ($symbols);
for my $symname (sort keys %main::)
{
    my ($shouldPrint) = 1;

    # ignore some data that we don't care about: %main::, %SIG, %Carp:
+:, etc.
    next if $symname =~ /::$/ || $symname eq 'SIG';
    
    if (defined @$symname)
    {
    $symbols .= "\@$symname:\n";
    $symbols .= Dumper @$symname;
    }
    elsif (defined %$symname)
    {
    $symbols .= "\%$symname:\n";
    $symbols .= Dumper %$symname;
    }
    elsif (defined $$symname)
    {
    $symbols .= "\$$symname: \"$$symname\"\n";
    }
    elsif (defined &$symname)
    {
    $symbols .= "sub $symname\n";
    }
    else
    {
    $symbols .= "unrecognized symbol: $symname\n";
    }
}
print "\n==================\n$symbols\n==================\n";
