Turn your Moose class into a Singleton
A singleton is a class that has only one instance in an application. "MooseX::Singleton" lets you easily upgrade (or downgrade, as it were) your Moose class to a singleton. All you should need to do to transform your class is to change "use Moose" to "use MooseX::Singleton". This module uses metaclass roles to do its magic, so it should cooperate with most other "MooseX" modules.
