NAME
    MooseX::ClassAttribute - Declare class attributes Moose-style

SYNOPSIS
        package My::Class;

        use Moose;
        use MooseX::ClassAttribute;

        class_has 'Cache' =>
            ( is      => 'rw',
              isa     => 'HashRef',
              default => sub { {} },
            );

        __PACKAGE__->meta()->make_immutable();

        no Moose;
        no MooseX::ClassAttribute;

        # then later ...

        My::Class->Cache()->{thing} = ...;

DESCRIPTION
    This module allows you to declare class attributes in exactly the same
    way as object attributes, using "class_has()" instead of "has()".

    You can use any feature of Moose's attribute declarations, including
    overriding a parent's attributes, delegation ("handles"), and attribute
    metaclasses, and it should just work. The one exception is the
    "required" flag, which is not allowed for class attributes.

    The accessor methods for class attribute may be called on the class
    directly, or on objects of that class. Passing a class attribute to the
    constructor will not set it.

FUNCTIONS
    This class exports one function when you use it, "class_has()". This
    works exactly like Moose's "has()", but it declares class attributes.

    One little nit is that if you include "no Moose" in your class, you
    won't remove the "class_has()" function. To do that you must include "no
    MooseX::ClassAttribute" as well.

  Implementation and Immutability
    This module will add a role to your class's metaclass, See
    MooseX::ClassAttribute::Role::Meta::Class for details. This role
    provides introspection methods for class attributes.

    Class attributes themselves do the
    MooseX::ClassAttribute::Role::Meta::Attribute role.

    There is also a MooseX::ClassAttribute::Meta::Method::Accessor which
    provides part of the inlining implementation for class attributes.

  Cooperation with Metaclasses and Traits
    This module should work with most attribute metaclasses and traits, but
    it's possible that conflicts could occur. This module has been tested to
    work with "MooseX::AttributeHelpers".

DONATIONS
    If you'd like to thank me for the work I've done on this module, please
    consider making a "donation" to me via PayPal. I spend a lot of free
    time creating free software, and would appreciate any support you'd care
    to offer.

    Please note that I am not suggesting that you must do this in order for
    me to continue working on this particular software. I will continue to
    do so, inasmuch as I have in the past, for as long as it interests me.

    Similarly, a donation made in this way will probably not make me work on
    this software much more, unless I get so many donations that I can
    consider working on free software full time, which seems unlikely at
    best.

    To donate, log into PayPal and send money to autarch@urth.org or use the
