59 This module provides a simple counter attribute, which can be
60 incremented and decremented.
62 If your attribute definition does not include any of I<is>, I<isa>,
63 I<default> or I<handles> but does use the C<Counter> trait,
64 then this module applies defaults as in the L</SYNOPSIS>
65 above. This allows for a very basic counter definition:
67 has 'foo' => (traits => ['Counter']);
