NAME
       MooseX::Attribute::ChainedClone - Attribute that returns a cloned
       instance

VERSION
       version 1.0.1

SYNOPSIS
	 package Test;
	 use Moose;

	 has debug => (
	     traits => [ 'ChainedClone' ],
	     is => 'rw',
	     isa => 'Bool',
	     default => 0,
	 );

	 sub complex_method
	 {
	     my $self = shift;

	     #...

	     print "helper message" if $self->debug;

	     #...
	 }

	 sub clone {
	     my $self = shift;
	     # custom clone code here
	     # defaults to:
	     return bless { %$self }, ref $self;
	 }

	 1;

       Which allows for:

	   my $test = Test->new;
	   $test->debug(1)->complex_method; # debug enabled
					    # complex_method is called on a cloned instance
					    # with debug set to 1

	   $test->complex_method;	    # debug is still disabled on $test

	   $test->debug(1); # returns a cloned $test instance with debug set to 1
	   $test->debug;    # returns 0

DESCRIPTION
       MooseX::Attribute::ChainedClone is a Moose Trait which allows for
       method chaining on accessors by returning a cloned instance of $self on
       write/set operations.

       If $self has a "clone" method, this method is invoked to clone the
       instance.  This allows for easy integration with MooseX::Clone or any
       custom made clone method. If no "clone" method is available, the new
       instance is build using "bless { %$self }, ref $self".
