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).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
