Calling an instance constructor? Yuck! If you want to
clone an object, use the right tool, such as
Clone:
use strict;
use Clone qw(clone);
my $foo = foo->new(5);
my $bar = clone($foo);
print $bar->id(), "\n";
package foo;
use strict;
sub new {
my ($class,$id) = @_;
my $self = {
id => $id || 42,
};
return bless $self,$class;
}
sub id {
my ($self,$id) = @_;
return $self->{id} unless $id;
$self->{id} = $id;
}
or provide your own clone() method for the class. I really
recommend that you read TheDamian's excellent book,
Object Oriented Perl, by the way.

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).
