I'm trying to create a new Tk widget derived from a Tk::Label. It works okay for the most part, but I discovered that the -foreground option doesn't seem to be getting passed. I've simplified the code to the following: 
package Tk::Foon;

use base qw(Tk::Derived Tk::Label);
Construct Tk::Widget 'Foon';

sub ClassInit  
{
  my($class, $mw) = @_;
  $class->SUPER::ClassInit($mw);
}

sub Populate
{
  my($self, $args) = @_;
  $self->SUPER::Populate($args);
  $self->ConfigSpecs('DEFAULT' => [ 'SELF' ]); 
}

[download]

And some test code: 

#!/usr/bin/perl -w
use strict;
use Tk;
use Tk::Foon;

my $mw = MainWindow->new;
my $l = $mw->Foon(-background =>'blue', -foreground => 'red')->pack;
  
$l->configure(-text => 'happy');
 
MainLoop;

[download]

Running this, I get the background of the label blue as requested, but the foreground appears black rather than red. Any ideas?

Thanks!
