Re: Making a Copy of a template object

Hi Chris,

Where you have the statement:

$template2 = $template ;

Essentially what you are doing here is creating a variable $template2 that
points to the same object as referenced by $template.  An object in perl is
a blessed reference and so you have just made a copy of a reference.  So
$template2 and $template point to the same object.

If you wish to make a true copy of the object, you will need to look at
things like Data::Dumper or better still the Storage module which has freeze
and thaw subroutines.  Hopefully this will achieve what you want.

All the best.

Regards,
Damien.
