- isa => 'Num',
- default => sub { 0 },
- provides => {
- inc => 'inc_counter',
- dec => 'dec_counter',
- reset => 'reset_counter',
- }
- );

-=head1 DESCRIPTION
-
-This module provides a simple counter attribute, which can be
-incremented and decremeneted.
-
-If your attribute definition does not include any of I<is>, I<isa>,
-I<default> or I<provides> but does use the C<Counter> metaclass,
-then this module applies defaults as in the L</SYNOPSIS>
-above. This allows for a very basic counter definition:
-
- has 'foo' => (metaclass => 'Counter');
- $obj->inc_foo;
-
