=head1 NAME 

Moose::Autobox - Autoboxed wrappers for Native Perl datatypes 

=head1 SYNOPOSIS

  use Moose::Autobox;
  
  print 'Print squares from 1 to 10 : ';
  print [ 1 .. 10 ]->map(sub { $_ * $_ })->join(', ');

=head1 DESCRIPTION

Moose::Autobox provides an implementation of SCALAR, ARRAY, HASH
& CODE for use with L<autobox>. It does this using a hierarchy of 
roles in a manner similar to what Perl 6 I<might> do. This module, 
like L<Class::MOP> and L<Moose>, was inspired by my work on the 
Perl 6 Object Space, and the 'core types' implemented there.

=head2 A quick word about autobox

The L<autobox> module provides the ability for calling 'methods' 
on normal Perl values like Scalars, Arrays, Hashes and Code 
references. This gives the illusion that Perl's types are first-class 
objects. However, this is only an illusion, albeit a very nice one.
I created this module because L<autobox> itself does not actually 
provide an implementation for the Perl types but instead only provides 
the 'hooks' for others to add implementation too.

=head2 Is this for real? or just play?

Several people are using this module in serious applications and 
it seems to be quite stable. The underlying technologies of L<autobox>
and L<Moose::Role> are also considered stable. There is some performance
hit, but as I am fond of saying, nothing in life is free. If you have 
any questions regarding this module, either email me, or stop by #moose
on irc.perl.org and ask around.

=head2 Adding additional methods

B<Moose::Autobox> asks L<autobox> to use the B<Moose::Autobox::*> namespace 
prefix so as to avoid stepping on the toes of other L<autobox> modules. This 
means that if you want to add methods to a particular perl type 
(i.e. - monkeypatch), then you must do this:

  sub Moose::Autobox::SCALAR::bar { 42 }

instead of this:

  sub SCALAR::bar { 42 }

as you would with vanilla autobox.

=head1 METHODS

=over 4

=item B<mixin_additional_role ($type, $role)>

This will mixin an additonal C<$role> into a certain C<$type>. The 
types can be SCALAR, ARRAY, HASH or CODE.

This can be used to add additional methods to the types, see the 
F<examples/units/> directory for some examples.
