Monks, please bear with me here, my OO vocabulary is not always accurate :P
I am concerned about one of the ways I have used to pass an object between classes, using bless.
$job is an object reference to a hash in the package oo::job
and $job is an object I am passing to the constructor oo::gui::defaultjob->new
once in the constructor, 
package oo::gui::defaultjob;
use strict;

sub new {
 my $self = shift;
 my $job = shift;
 my $oldclass = ref $job;
 bless $job, $self;
# Call methods of defaultjob on $job, since they depend on
# the hash as setup by oo::job
 MainLoop; # Invoke Tk, allowing user to gui'ly modify the job
 return bless $job , $oldclass
}

Thus $job is returned as belonging to the oo::job package.
My question : What nastiness have I introduced here ? or is this an over-complication of an easier way.
Reading the Damian Conway's OOPerl book, which is making the cracks which flood the brain with light, but I am certainly still learning.
Constructive Abuse only pls!
