module that provides a simple object container
Object::Container is an object container with an OO interface. It is used to make singletons out of ordinary classes. . For example, if you want to have a single instance of WWW::Mechanize throughout a program, you can do Object::Container->register('WWW::Mechanize') somewhere and then you can retrieve that instance of WWW::Mechanize from anywhere else with Object::Container->get('WWW::Mechanize'); . Class::Singleton is a similar module, which makes subclasses singletons. Unlike Class::Singleton, Object::Container can make any class a singleton. . Object::Registrar is another similar module, but it does not support lazy loading.
