I'd say explicitly pass the data back with a subroutine call.

package Config;
require Exporter;
our @ISA=qw(Exporter);
our @EXPORT_OK=qw(read_config);

sub read_config {
  my %data;
# read configuration file in and 
# put values into a hash
 return \%data;
}

In the modules that use Config: 
package One;
use Config qw(read_config);

my $conf = read_config();

Granted, you then have your configuration data in a hash and need to call it with e.g. $conf->{logfile} instead of $logfile but IMO that's cleaner anyway.


There are ten types of people: those that understand binary and those that don't.
