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 gives your class an C method that can be used to get a handle on the singleton. It's actually just an alias for C. + +Alternatively, C<< YourPackage->method >> should just work. This includes +accessors. + +=head1 TODO + +=over + +=item Always more tests and doc + +=item Fix speed boost + +C invokes C every time C<< Package->method >> is called, which +incurs a nontrivial runtime cost. I've implemented a short-circuit for this +case, which does eliminate nearly all of the runtime cost. However, it's ugly +and should be fixed in a more elegant way. + +=back + +=head1 BUGS + +All complex software has bugs lurking in it, and this module is no +exception.
