Moose::Autobox(3) User Contributed Perl Documentation Moose::Autobox(3)

Moose::Autobox - Autoboxed wrappers for Native Perl datatypes

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

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

The 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 autobox itself does not actually provide an implementation for the Perl types but instead only provides the 'hooks' for others to add implementation too.

Several people are using this module in serious applications and it seems to be quite stable. The underlying technologies of autobox and Moose::Role are also considered stable. There is some performance hit, but as I am fond of saying, nothing in life is free. Note that this hit only applies to the use of methods on native Perl values, not the mere act of loading this module in your namespace.
If you have any questions regarding this module, either email me, or stop by #moose on and ask around.

Moose::Autobox asks autobox to use the Moose::Autobox::* namespace prefix so as to avoid stepping on the toes of other 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.

mixin_additional_role ($type, $role)
This will mixin an additional $role into a certain $type. The types can be SCALAR, ARRAY, HASH or CODE.
This can be used to add additional methods to the types, see the examples/units/ directory for some examples.

All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
