Here is a similar solution inspired by your code.
package Chain;
sub new {
my $proto = shift;
my $self = {obj => shift};
bless $self, $proto;
return $self;
}
sub AUTOLOAD {
my $self = shift;
my ( $method ) = ( our $AUTOLOAD =~ /.*::(.*)/ );
$self->{obj}->$method( @_ );
$self;
}
1;
Now we can just do Chain->new($obj) and call methods on that object expecting the object itself as a return. I'm sure this could be cleaned up to handle errors etc.
use strict;
use warnings;
use lib ".";
use Chain;
use Test;
my $t = new Test;
$t->hello;
$t->cool(1,2);
Chain->new($t)
->test
->hell(1,2,3)
->say("hello");

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).
