If moritz's second reading is correct and you want to print a representation of your object then you could look at overload to associate a subroutine with stringification of your object. Something along the lines of

use strict;
use warnings;

package MyModule;

use overload q{""} => q{printObject};

sub new
{
...
}
...
sub printObject
{
    # print your attributes here
}

package main;

my $obj = MyModule->new(some => q{args});
...
print qq{$obj};
...

I'm not sure either from your post whether this is what you want but here's hoping.
