NAME

       Acme::Damn - 'Unbless' Perl objects.

SYNOPSIS

         use Acme::Damn;

         my $ref = ... some reference ...
         my $obj = bless $ref , 'Some::Class';

         ... do something with your object ...

            $ref = damn $obj;   # recover the original reference (unblessed)

         ... neither $ref nor $obj are Some::Class objects ...

DESCRIPTION

       Acme::Damn provides a single routine, damn(), which takes a blessed reference (a Perl object), and
       unblesses it, to return the original reference.

   EXPORT
       By default, Acme::Damn exports the method damn() into the current namespace. Aliases for damn() (see
       below) may be imported upon request.

   Methods
       damn object
           damn() accepts a single blessed reference as its argument, and returns that reference unblessed. If
           object is not a blessed reference, then damn() will "die" with an error.

       bless reference
       bless reference [ , package ]
       bless reference [ , undef ]
           Optionally, Acme::Damn will modify the behaviour of "bless" to allow the passing of an explicit
           "undef" as the target package to invoke damn():

               use Acme::Damn  qw( bless );

               my  $obj = ... some blessed reference ...;

               # the following statements are equivalent
               my  $ref = bless $obj , undef;
               my  $ref = damn $obj;

           NOTE: The modification of "bless" is lexically scoped to the current package, and is not global.

   Method Aliases
       Not everyone likes to damn the same way or in the same language, so Acme::Damn offers the ability to
       specify any alias on import, provided that alias is a valid Perl subroutine name (i.e. all characters
       match "\w").

         use Acme::Damn qw( unbless );
         use Acme::Damn qw( foo );
         use Acme::Damn qw( unblessthyself );
         use Acme::Damn qw( recant );

       Version 0.02 supported a defined list of aliases, and this has been replaced in v0.03 by the ability to
       import any alias for "damn()".

WARNING

       Just as "bless" doesn't call an object's initialisation code, "damn" doesn't invoke an object's "DESTROY"
       method. For objects that need to be "DESTROY"ed, either don't "damn" them, or call "DESTROY" before
       judgement is passed.

ACKNOWLEDGEMENTS

       Thanks to Claes Jacobsson <claes@surfar.nu> for suggesting the use of aliases, and Bo Lindbergh
       <blgl@cpan.org> for the suggested modification of "bless".
