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. I can't think of any reason why you might want to do this, but just because it's of no use doesn't mean that you shouldn't be able to do it.

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.

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.
