Thanks for the exposition; my inclination regarding a simple module is as follows:

package MyModule;
use strict;
use warnings;
use diagnostics;
use Carp;

our $VERSION = 1.08;

sub see_me
{
   my $foo = shift;
   print "\t\tDo you see this: $foo?\n";
}

1;

__END__
last line of the module needs to be true;
last line of the _file_ need not be true:
0;

The above module is exercised by the following script:

exercise_my_module.pl

#!/c/opt/perl/bin/perl
use strict;
use warnings;
use diagnostics;
use Carp;
use MyModule  1.05;   
#use MyModule  1.10;  # will fail

MyModule::see_me( 8 );

__END__
