MooseX::Singleton - turn your Moose class into a singleton

-Version 0.08, released 24 May 08

=head1 SYNOPSIS
package MyApp;
C<use MooseX::Singleton>. This module uses a new class metaclass and instance
metaclass, so if you're doing metamagic you may not be able to use this.
-C<MooseX::Singleton> gives your class an C<instance> method that can be used to get a handle on the singleton. It's actually just an alias for C<new>.
+C<MooseX::Singleton> gives your class an C<instance> method that can be used to
+get a handle on the singleton. It's actually just an alias for C<new>.
Alternatively, C<< YourPackage->method >> should just work. This includes
accessors.
+If you need to reset your class's singleton object for some reason (e.g.
+tests), you can call C<< YourPackage->_clear_instance >>.
