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 DESTROYed, 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.
