What's next with acts_as_state_machine?

I've been using acts_as_state_machine and there seems to be at least two convenience methods missing that I find quite useful:

1. next_state - what state will we be transitioning to
2. next_states - list of states that we still need to transition to

Drop the following in a suitable place (your model using acts_as_state_machine will do) and abuse it to your hearts content:

# Monkey patch acts_as_state_machine to allow us to see what the next states are
# for the current state
module ScottBarron
 module Acts
   module StateMachine
     module InstanceMethods
         def next_state(state=nil)
           state ||= current_state()
           self.class.read_inheritable_attribute(:transition_table).each_value do |event|
             event.each do |transition|
               return transition.to if transition.from == state 
             end
           end
           nil
         end
        
         def next_states(state=nil)
           state ||= current_state()
           states = [] 
           while state = next_state(state)
             states << state            
           end            
           states          
        end       
      end    
    end  
  end
end 

Thanks to Lourens Naude's' post on acts_as_state_machine for providing me with some ideas and to Scott Barron for the great acts_as_state_machine plugin.
