Re: "cleaning out" object data

[pelagic]

Ok now, after frodo72's comment, I can't resist and give you a code example:

use strict;
use Data::Dumper; $Data::Dumper::Indent = 1;

my $o1 = gugus->new;
my $o2 = $o1;
print 'This is before Forsaken_cleaning: ', Dumper $o1, $o2;

$o1 = $o1->Forsaken_clean;
print "\n", 'This is after Forsaken_cleaning: ', Dumper $o1, $o2;

my $o3 = gugus->new;
my $o4 = $o3;
print "\n", 'This is before rev_1318_cleaning: ', Dumper $o3, $o4;

$o3 = $o3->rev_1318_clean;
print "\n", 'This is after rev_1318_cleaning: ', Dumper $o3, $o4;

package gugus;
sub new {
    my $class = shift;

    my $self  = { 'k1' => 4711 };

    bless $self, $class;

    return $self;
}
sub Forsaken_clean{
    my $self = shift;
    foreach (keys %$self) {
        delete $self->{$_};
    }
    $self;
}
sub rev_1318_clean{
    my $self = shift;
    %$self = ();
}

__RESULT__
This is before Forsaken_cleaning: $VAR1 = bless( {
  'k1' => 4711
}, 'gugus' );
$VAR2 = $VAR1;

This is after Forsaken_cleaning: $VAR1 = bless( {}, 'gugus' );
$VAR2 = $VAR1;

This is before rev_1318_cleaning: $VAR1 = bless( {
  'k1' => 4711
}, 'gugus' );
$VAR2 = $VAR1;

This is after rev_1318_cleaning: $VAR1 = 0;
$VAR2 = bless( {}, 'gugus' );

Unless someone comes up with a idea not mentioned here, OP's solution is the way to go (or if you like it sweetened BrowserUk's).
