=head1 NAME
Class::Field - Class Field Accessor Generator

=head1 SYNOPSIS
package Thing;
use Class::Field qw'field const';
field 'this';
field 'list' => [];
field 'map' => {};
field 'that', -init => '$self->setup_that';
field 'circular_ref' => -weaken;
const 'answer' => 42;
=head1 DESCRIPTION
Class::Field exports two subroutines, C<field> and C<const>. These functions
are used to declare fields and constants in your class.
Class::Field generates custom code for each accessor that is optimized
for speed.
=head1 FUNCTIONS
=over
=item C<field>
Defines accessor methods for a field of your class:
package Example;
use base 'Parent';
use Class::Field qw'field const';
field 'foo';
field bar => [];
sub lalala {
my $self = shift;
$self->foo(42);
push @{$self->{bar}}, $self->foo;
}
The first parameter passed to C<field> is the name of the attribute being
defined. Accessors can be given an optional default value. This value will be
returned if no value for the field has been set in the object.
=item C<const>
const bar => 42;
The C<const> function is similar to <field> except that it is immutable.
It also does not store data in the object. You probably always want to
give a C<const> a default value, otherwise the generated method will be
somewhat useless.
=back
=head1 NOTE
This code was taken directly out the Spiffy module for those people who just
want this functionality without using the rest of Spiffy.
