[perl-win32-gui-hackers] Exporter fails with 'use Win32::GUI'

[Arthur S. <asc...@ve...>]

I can't get the 'Exporter' to work when I 'use Win32::GUI'. Example code
included below. Any fix? Anything I misunderstand?

Cygwin Perl v5.8.7
Win32::GUI  Win32-GUI-1.03 (12 Apr 2006)


art

# GUI.pl
package GUI;

use GUI::Win;                   # Windows GUI Examples

  WindowStart();                # Undefined subroutine &GUI::WindowStart called
at GUI.pl line 11.

# GUI/Win.pm
package GUI::Win;

use Win32::GUI;                 # works when commented, fails when not

use Exporter;                   # Export symbols

use vars qw($VERSION @ISA @EXPORT);

our @ISA         = qw(Exporter);
our @EXPORT      = qw(WindowStart);
our $VERSION     = '1.00.00';

sub WindowStart {

  print "ABC\n";

  return 1;

} ### WindowStart


1;

Don't use package GUI.  The following code appears near the top of GUI.pm:

   # Reserves GUI in the main namespace for us (uhmmm...)
   *GUI:: = \%Win32::GUI::;

That will effectively move anything you define in the package GUI into 
the package Win32::GUI - which already has it's own exporter, so I'm not 
surprised you're seeing problems.

I've looked at it a number of times and would like to remove it, but I 
don't know it's history.  I assume it's there for historic backwards 
compatibility reasons, and that the package was originally just called 
'GUI' rather than 'Win32::GUI' - this line would have kept old code 
running - but I haven't been around long enough to be sure there isn't 
anything else that depends on this.

Does anyone know for sure?  Should we remove it?

Better sooner than later.

I was here at that times when when it was called GUI.
Dada's old examples used it, but I saw no code using it anymore for years.

I'll give it another few days for anyone to object, otherwise I'll 
remove it.
