       This extensions allows classes to flag certain methods as being required to be implemented by a subclass,
       much as a Moose::Role does with 'requires'.

       MooseX::AbstractMethod - Declare methods requirements that must be satisfied

abstractabstract() allows one to declare a method dependency that must be satisfied by a subclass before it is
       invoked, and before the subclass is made immutable.

           abstract 'method_name_that_must_be_satisfied';

   requiresrequires() is a synonym for abstract() and works in the way you'd expect.

       The development version is on github at <http://github.com/RsrchBoy/moosex-abstractmethod> and may be
       cloned from <git://github.com/RsrchBoy/moosex-abstractmethod.git>

           use Moose;
           use MooseX::Abstract;

           requires 'bar';

           # synonm to 'requires'
           abstract 'foo';

       As in the synopsis, simply mark certain methods as being required by subclasses by passing their names to
       "abstract" or "requires".  This will cause a method of the same name to be installed in the class that
       will die horribly if it's ever called.  Additionally, when a class is made immutable, all of its methods
       are checked to see if they're marked as abstract; if any abstract methods exists that were not created in
       the current class, we die horribly.

       Checking for method satisfaction on make_immutable isn't perfect, but AFAICT it's the most reasonable
       approach possible at the moment.  (Corrections welcome.)
