I am having problems w/ GetOption() not dying when an option is missing a value and use '--' as end-of-options marker. Below is how i tried to invoke it... 
  screw.perl --debug --

...and screw.perl...

#!/usr/local/bin/perl -w

use strict;
use Getopt::Long;

my %opt = ( 'debug' => 'g1' ); 

GetOptions( 'debug=s' => \$opt{'debug'} )       
  || die ("$!\n");

while ( my ($k , $v) = each %opt )
{
  printf "%s = %s\n" , $k, $v; 
}

I was expecting the program to die instead of seeing...

  debug = --

...'--' is not swallowed (which has been the intention all along), however, when usage is one of the following... 

  screw.perl -debug= --
  screw.perl --debug= --

Mind you above is only the minimal text to show my problem. I had tried various combinations of configure options (for the module) to no avail. And yes, writing a '=' instead of just ' ' is not preferred.

I am writting a wrapper program which has often used options for the wrapped program in a hash; other options are passed as is. Specifying (on command line) any option to pass as is before the ones set in GetOptions() is hard to work w/.

All the problems want me to write my own damn option parsing module. How do people cope when writing a a Perl wrapper which accepts known & unkwon options for the wrapped program?
