Excuse me, but you're not being fair here. I really don't know why you need to re-assign to the
$o1 and
$o3 objects:
# ... when you call Forsaken_clean
$o1 = $o1->Forsaken_clean;
# ... and when you call rev_1318_clean
$o3 = $o3->rev_1318_clean;
The assignment risks to spoil the left hand side without added value: the call itself already cleans up the objects. And it really does spoil
$o3, as we can see comparing the cleaning functions:
sub Forsaken_clean{
my $self = shift;
foreach (keys %$self) {
delete $self->{$_};
}
$self;
}
sub rev_1318_clean{
my $self = shift;
%$self = ();
}
The former has a
$self as last statement, while the latter hasn't and it's returning nothing. Fixing is trivial, just add a line in
rev_1318_clean:
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 = ();
$self; # This is the added line
}
__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 = bless( {}, 'gugus' );
$VAR2 = $VAR1;

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).
