       Class::Field exports two subroutines, "field" and "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.

       "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 "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.

       "const"
               const bar => 42;

           The  "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 "const" a default value,  otherwise  the  generated
           method will be somewhat useless.

       This  code  was  taken  directly  out the Spiffy module for those people who just want this functionality
       without using the rest of Spiffy.

           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;
