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.
