After seeing characterstics of private in perl it reminded me of a project I had been working on where I had used the following to create a private like method:

package Foo;
use strict;
use warnings;

my $_init_ = sub {
  my $self = shift;
  print STDERR ref($self) . "::_init_ called\n";
};

sub new {
  my $type = shift;
  my $class = ref($type) || $type;
  my $self = {
    attribute1 => undef,
    attribute2 => undef,
  };
  bless $self,$class;
  $self->$_init_();
  return $self;
}

1;
[download]

And then the usage went like this:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use lib "./";
use Foo;

my $foo = new Foo();
print Dumper(\$foo),"\n";
[download]

And I was able to subclass as needed, such as:

package Bar;
use strict;
use warnings;
use base qw( Foo );
 
1;
[download]

With the useage similar to the Foo usage:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use lib "./";
use Bar;
 
my $bar = new Bar();
print Dumper(\$bar),"\n";
[download]

My question is, will this cause problems down the line when the application as a whole gets really complex? Is this safe and if not, why?
