libclass-accessor-chained-perl 0.01.1~debian-4 (amd64 binary) in ubuntu disco

 A chained accessor is one that always returns the object when called
 with parameters (to set), and the value of the field when called with
 no arguments.
 .
 Class::Accessor::Chained subclasses Class::Accessor in order to provide
 the same mk_accessors interface.
