I've found Data::Perl::Counter where Matthew Phillips considers a counter as a value able of both incrementing and decrementing, what seem quite logical now (my initial point of view was that a counter always increased). I'm trying to contact with Mathew in order to know his opinion about of adding the new module to the current structure (something like Data::Perl::Counter::Delta) and make it compatible with his counter class.
