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");
