Fellow Monasterians,

I was reading an old node called What shortcuts can I use for linking to other information? and it raised more questions.

In my earlier days as a Perl coder I used what perlmod calls a "tradition non-OO module" to share code. I never understood all the "EXPORTing" stuff, and all the typing of subroutine names was tedious, but the approach worked fine.

For the past few years I've used CGI::Application exclusively for all my web applications (95% of what I use Perl for), and have been using a "simplified" approach of use base qw(SomeModule), which works well and is easier on the wrist.

My question is simply, are there any caveats/ramifications to abandoning the non-OO method and exclusively using the "OO-inherited-class" module (for want of a better name)? Pluses? Minuses?

Some simplified examples:

PREVIOUSLY USED METHOD

#common routines to share among all modules
package Common;

use strict;
use Exporter;
use vars qw(@ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);
*import= \&Exporter::import;
@EXPORT = ();
@EXPORT_OK = qw(get_today get_setup);
%EXPORT_TAGS = ( All => [qw(&get_today &get_setup)]);

sub get_today {
   #get date
}
sub get_setup {
   #get application parameters
}
1;

#example of a calling module
package SomeFile1;
use strict;
use Common qw(:All);

#...CGI::Application setup, etc...

sub initialize {
   my $self = shift;
   
   my $day = $self->get_today();
   my $setup = $self->get_setup();
}
1;

NEWER METHOD

#code to share
package Super;
use strict;
use base 'CGI::Application';

sub get_today {
   #get date
}
sub get_setup {
   #get application parameters
}
1;

#example of calling module
package SomeFile1;
use strict;
use base 'Super';

#...CGI::Application setup, etc...

sub initialize {
   my $self = shift;
   
   my $day = $self->get_today();
   my $setup = $self->get_setup();
}
1;

Thanks in advance
